View Full Version : Is Comet Ison Really A Comet?
Mandala
19th August 2013, 22:37
I'm not anywhere nearly proficient at interpreting pictures from the Huble Telescope. I have to question if it could be possible that what we believe to be Comet Ison is something else; like a ship?
I don't know, but some of you who are adept at understanding space photographs might say, "That's perfectly normal, and what a comet should look like.
I have noticed a few recent videos posing that question, but I don't have the knowledge to make a claim. What do you think?

looks like two EMV's (energy rods) checking out this comet ... they usually stay around the sun ... the is a dwarf race of ET's that observe earth, they use these energy ships ... who knows , I cannot look that direction , till it gets further from the sun ... one thing for sure is, if it is EMV's , it will change shape at any time ...

never mind i should have watched the second video before I commented. So now my response to this is, holy cow. Lets find more images and see if we can find more that prove this theory. I tried to lower the exposure on this but all I got was a round white blob. I obviously do not have the right software to tweak around with it.

Here is what someone posted on another forum about this image....
Hubble took those pics while tracking the stars. The comet was moving while the pic was being taken and that’s why it shows up as a line instead of a dot. There are 3 separate images combined to make this picture, so that’s why there are 3 separate lines. Nothing mysterious about this and it is quite common for comet images.
They were trying to show the comet and the faint galaxies in the background without either the comet or the stars showing movement. For the comet, they just boosted the brightness and that merged the 3 separate central condensations of each comet image into one big one. I’ve done this myself at times with my comet images. Its a quick and dirty way to get the comet and stars to “freeze” and not show movement. But, if you examine it closely like was done in the video, you’ll see the separate comet images and the movement that the comet made during the relatively long exposures that were used.

when i read comments such as this one regarding a possible discovery of a cover up i become suspicious. there are thousands of disinformation agents out and about who are quick to dispel such notions and they are very good at it. on the other hand it could be legitimate. i just keep an open mind to them.

Also besides the post processing creating ghosts and strange effects, comets are also composed primarily of ice, so they can reflect in odd ways especially its corona.

This is the response from "BPEarthWatch" on youtube about the "Parallax".
Quote:
"Parallax is displacement of the apparent position of an object viewed from two lines of sight. In order for this to be parallax you require 1 object (ISON) as seen from 2 lines of sight and measures the angle of inclination between those 2 lines, Hubble is only 1 line of sight, this could not and can not be parallax the parameters are just not there."

It's been said multiple times on this forum already, but for those that have missed it:
Any mysterious/unusual/anomalous astronomical events will be picked up and discussed by the thousands of amateur astronomers all over the world - the vast majority of which have no connection with or can be controlled by NASA, secret world government, the ANUNNAKI (or probably any alien or inter-dimensional forces) or anyone/anything else for that matter.
If such an astronomical event were to appear, a subtle (or clumsy, heavy-handed) cover story published by NASA or any official body will be discussed, dissected and derided by these astronomers and spread across the web on their forums and websites - most of which anyone can look at without charge or registration.
Please don't forget that for any conspiracy story it is not just "us" (the free-thinking, enlightened alternative community) against "them" (the bad guys trying to hide the truth from "us"). There are thousands of unbiased, free-thinking, experienced, trained specialists in their field who would expose any real nonsense after multiple confirmations between themselves.
Such stuff just cannot be covered up for long - if at all.

Hubble is an orbiting telescope, hence it has 2 lines of sight from opposite sides of the globe, and all the other lines of sight in between.

There are huge forums dedicated to amateur astronomers, most of them owning multiple telescopes. Some of those scopes cost as much as a new car, some more. Some even have their own observatories.
I'll give you an idea. An image of what one customer owns. one for him, a 32" scope and a second one (his earlier buy) for his daughters -an 18" unit.
http://webstertelescopes.com/C32_D18.jpg
http://webstertelescopes.com/scopes_currently_in_stock.htm
They have that list 'in stock', they can make as big as a 60" unit. Things have really moved along in the world of telescopes and NO, no one could hide 'nibru' from them (all those amateur astronomers) at the distance "they" say it is from us....
Thousands from the one company and dozens of companies, most of them bigger than this one company.
Tens and tens of thousands of amateur astronomers with huge scopes, all looking at comet Ison. No joke.
~~~~~~~~~~~~~~~
Most importantly, in order to gauge exactly what this all means.... how much of a change is this, since ...oh.. the turn of the century?
Well, here's a list of the world's biggest 'scopes, at the turn of the century (1900). This will give you an idea HOW difficult it would be to hide ANYTHING that is in the skies from modern amateur astronomers. When 32"-40"-60" telescopes are now becoming easily possible, and 25" sizes are downright common.
http://en.wikipedia.org/wiki/List_of_largest_optical_telescopes_in_the_19th_century
I'm saying that 10's of thousands of amateur astronomers now have more observing horsepower than 99.99% of the professional astronomers had at the turn of the century.
And.. someone is going to hide something in the skies...from that crew?
I don't think so.
In this list, of the now, and the 20th century.....:
http://en.wikipedia.org/wiki/List_of_largest_optical_telescopes_in_the_20th_century
....... 60" units are listed (1960's or so). Note that this company, Webster (linked above), can make you a 60", today, in 2013. So you can have a home scope bigger than pro scopes from the 60's-70's. Guys are buying these things and building their own observatories.

Back on topic; yes indeed!
The point is, how come all the amateur astronomers across the world have NOT spotted that Comet Ison is in three parts? Carmody has already shown the type of telescopes some amateur astronomer use.
What's wrong with the parallax explanation?
Is the guy giving the voice-over in the video a qualified (or even unqualified) astronomer, or just a purveyor or conspiracy fear-porn and disinformation?
Like I said, this stuff cannot be covered up. And why should it be? If the comet does break up, that would be seen and reported as an interesting development, although not the first time a comet has split up or disintegrated as it approached the sun.
Soon enough we'll be able to see with our own eyes...
(Why is time spent claiming stuff like this is 'covered up'?)

Okay, I really hesitated to post this, but then decided to anyway. Alfred Lamont Weber has interviewed a guy many times called "Tolec", who claims to be a contactee, not a channel. He says he speaks with the Andromeda people on their biosphere.
I can see you shaking your heads and saying, " oh no, what a dufus".
However, wouldn't it be nice to think that maybe this guy isn't delusional , or perhaps planted by an alphabet agency, and this could be a harbinger of first contact.
I'm only hoping, because I really want this to happen. I want contact and disclosure. I think it would be fantastic if things could play out this way and there was absolutely nothing the elites could do about it. Maybe this is why there pushing for a war.

Thanks for posting. I too would like to think this guy sincere, but is he just taking the **** to see who takes him seriously for mischievous fun?
If the 'biosphere' and 'escort ships' are anywhere near as big as he says, we'd be able to SEE them with a basic, half-decent telescope by now. The comet's visible nucleus is only about 3 miles across which we can see - that's only one percent of the '300 mile' diameter biosphere, which has - apparently - gone undetected.
I hope the Andromeda Council really exists and not just in some folks' heads. But how will we know?
(Nice music BTW.)
And when comet Ison comes and goes without incident, will these people fess-up and say they were mistaken - again? Nahh...

Is it just short memories or are people really nuts?

Have you ever heard of Comet Hale–Bopp and Heaven's Gate? Can we stop this madness? [...]

C'mon guys; basic questions we should be asking ourselves when we see stuff like this:
1) Does the Tianlian 1 satellite exist? Yes, but it's a communication satellite, is in orbit around the Earth and therefore is nowhere near the comet!
2) Where did the video come from and first appear? Well apparently it just appeared from the original poster.
3) Is that really a video of Ison? Well if it just 'appeared' from one source, have a guess...
4) Who is the guy making the video? What does he know about astronomy? He probably just makes hoax videos.
But hey, he may have stolen the video from a secret NASA source so there won't be an original one floating about in the public domain. So of course it may all be genuine, you can decide.
(The obvious fact that he got the satellite wrong cannot be incompetence. It's surely just a clue that this is bull sh*t for anyone who wants to do even the tiniest bit of checking!)

It's not clear from this video what the source of the image of the comet with the two circling moons is. The current images from amateur astronomers are nowhere near this detailed and close-up, so I would have to say CGI is likely.
Looks like if we had a really good telescope we could look for ourselves now. If you have a halfway decent telescope, you can see it next month. If you have a cheap telescope like mine, you probably have to wait longer!

From http://archive.stsci.edu/hla/ison :
Some bloggers have noted that the Comet C/2012 S1 (ISON) Hubble images (http://archive.stsci.edu/prepds/ison/) have some surprising features. Here we briefly explain the origin of the image structures.
Quick summary: The image is the result of combining 3 exposures that produce the 3 components, and the shapes are produced by the combined motion of the Hubble telescope and the comet. The images look exactly as expected.
http://archive.stsci.edu/hla/ison/combined.jpg
Comet C/2012 S1 (ISON)
Hubble, 2013 Apr 30
Combined 3-exposure image
The image from April 30, 2013 (released on July 16, 2013) using the F606W filter has attracted the most attention. That image (shown above) is the average of 3 separate Hubble exposures. The 3 exposures are available individually for display or download from the web page, as is the combined image. The table below shows the image of the comet in each of the 3 exposures along with information about the exposures.
Comet C/2012 S1 (ISON) Hubble observations on 2013 April 30 using F606W
http://archive.stsci.edu/hla/ison/exposure1.jpg
Exposure 1, 440 seconds
http://archive.stsci.edu/hla/ison/exposure2.jpg
Exposure 2, 440 seconds
http://archive.stsci.edu/hla/ison/exposure3.jpg
Exposure 3, 440 seconds
You can see that the 3 parts of the structure in the combined image result from the 3 different exposures. The comet itself does not have 3 pieces. They are an artifact that results from adding up the separate exposures.
The comet does not look the same in each exposure because both the comet and the Hubble telescope are moving during the exposure. The comet is blurred, just as a picture taken out the window of a moving car will be blurred. For this image the Hubble telescope was pointing very steadily and accurately at the background stars and galaxies rather than tracking the comet.
In this case, the largest part of the blurring is due to the motion of Hubble itself rather than the motion of the comet. Hubble is orbiting the Earth every 95 minutes. The third exposure ended 46 minutes after the start of the first exposure. During that time the telescope moved from one side of its orbit to the other, a distance of about 8000 miles (~13,000 km). Because the comet is relatively nearby (compared with the distant stars and galaxies), its apparent position among the stars changes due to the different viewing position. This effect is known as parallax. It is expected when observing Solar System targets, and can produce very obvious motion or blurring in images as Hubble whips around the Earth.
Smell the Roses
13th September 2013, 15:20
Yes, the NASA officially line is that the three parts come from the three different images and the parallax phenomenon. I'm not sure what their explanation is for having increased the brightness in the first place to make the three parts not apparent. Just to make a pretty picture? I don't want to spend a lot of time looking into it, because it's the government who is the source of these images. My usual philosophy with them is to assume they are lying unless it is proven otherwise. It will be nice when it is close enough to see with our own telescopes or our own eyes.

Mandala,
Two interesting questions are raised in this video:
1) If we accept the three images parallax explanation, why did NASA combine the images and increase the brightness?
2) They haven't done this composite image thing in the past with other comets, so why now?
I don't personally have a lot of attachment to whether ISON is a comet or not. Elsewhere people have said it's a friendly ET biosphere (sounds good), or a reptilian ship (hope not). It could be just a comet. The fact that NASA doth protest too much just feeds the fire.

13th September 2013, 16:46
Meh, to be honest, I don’t see how any of us can know what this is. I’m sure it’s just as unimportant as the many other space anomalies we speculated about in the past. Until I get my very own spacecraft I’ll reserve judgment while continuing to concentrate on more meaningful happenings within our atmosphere…not above it. Nasa is very good at creating distractions and keeping our heads in the clouds. I can hardly think of anything important that agency has done for mankind… other than filling them with inconsistent theories and ideologies. Oh, I do hear their memory foam mattresses are a big hit, btw. Keeping people sleeping comfortably sounds like something they are very good at doing…

Actually, they have! As best I know, it's standard practice with small moving objects. Stars effectively don't move relative to us (apart from taking the Earth's rotation into account), so this method of compiling a photo isn't necessary. They just use long exposures.
<--- Nick, can you confirm?
I do actually remember exactly the same conversation about Elenin, which some said was being accompanied by 'spaceships'. They were just image artifacts, generated in the same way.
I promise you guys: this is just a comet. Really! If it's not, I'll eat my hat with mayonnaise and ketchup and post the video on YouTube.

Nick Matkin
13th September 2013, 23:46
<--- Nick, can you confirm?
No, I'm sorry Bill I can't confirm - I really don't know enough about astrophotography to even speculate.
But as you say, it's just a comet. Where's the proper evidence to say it's anything else? A few Youtube videos with scary music and impressive but irrelevant graphics? I don't think they count, neither do any astronomers.
Unfortunately saying that over and over isn't going to convince those who think that this time it really is a spaceship/Planet X/Nibiru with its inhabitants coming to save/destroy humanity.
This one will run and run until we can all see it with our own eyes, then it will fade away back into space and nothing will have happened.
No one will then fess up and say all their hype was bull s**t and apologise to those who were taken in by it. Then the fiasco will be completely forgotten, until a few months later when there is bound to be another reported astronomical harbinger of salvation/destruction. And as if we've all been gripped by a collective amnesia, the hype will start again as if it were the first time...
A few will scream "ENOUGH! WE'VE HEARD IT ALL BEFORE", but alas it will fall on deaf ears.
So Bill, I'm with you. But oh; I really hope I'm wrong - I do so much want to see you eat your hat with with mayonnaise and ketchup - and mustard, please? ;)

Thanks for posting this Goivonni. It's yet another rational analysis that completely annihilates all the ridiculous comet fear-porn c**p that keeps appearing.
Perhaps those who claim that comet Ison is a plasma-shielded spaceship (and similar assertions) should put their money where their mouths are and state that if it does turn out to be just a comet, they'll very publicly donate say $5,000 to some charity and apologise for making stuff up.
I'm sure plenty of astronomers would commit to doing the same thing if it turns out to be anything other than a comet!
That should clear the air. What do you think?

What the so-called comet ISON, clearly a craft, perhaps even a collection of crafts, incoming at this time is doing, what might appear to be a fly-by in November but what could easily become a drop off and pick up stop-over... is also unclear.

Its closest approach to the Earth will be about 40 million miles (just under half the distance between the Earth and the Sun), on 26 December. If it's piloted by ETs, they took a wrong turn somewhere! :)

There's another site to add to the DISREGARD list:
The 'Internet Chronicle' at http://chronicle.su. This is a deliberately satirical site (and they state that openly), but many people miss the caveat. This was the source of the much-copied Edward Snowden: Solar-Flare ‘Killshot’ Cataclysm Imminent (http://www.chronicle.su/news/edward-snowden-solar-flare-killshot-cataclysm-imminent/) report, and quite a lot else that far too many people have fallen for and believed far too quickly.
One of their recent stories (Sept 11) was this one:
http://chronicle.su/news/top-terror-targets-hit-in-global-terror-blitz
which, poker-faced, states this:
After three consecutive weeks of the most elevated terror alert levels since 2001, synchronized attacks have nonetheless killed millions of innocent Americans on the twelfth anniversary of 9/11, bringing every major city in America to a standstill. New York City Homeland Security Agents report hundreds of Al-Qaeda agents infiltrated the Freedom Tower construction crew and filled the core of every concrete beam with nanothermite (etc etc etc)

Comet Chasing in September (http://cometchasing.skyhound.com/):
2012 S1 (ISON) (http://observing.skyhound.com/ISON.html) has the potential to be a "Great Comet" in the late fall of 2013.
2013 R1 (Lovejoy) is a new discovery by Terry Lovejoy of Australia on September 9.
2013 G5 (Catalina) may have disintegrated as there have been no observations reported since July.
2013 E2 (Iwamoto) is a new discovery by Masayuki Iwamoto of Japan on March 14. This comet passed perihelion on March 8, and should fade slowly.
C/2013 A1 (Siding Spring) is a new discovery by Robert McNaught on January 3. This comet will pass very close to Mars on the 19th of October 2014. It is not currently observable visually.
273P (was C/2012 V4) is a bright new SWAN discovery that has been linked to the "lost" comet D/1827 M1 (Pons-Gambart).
2012 CH17 has apparently disintegrated.

I probably could! (Add to the list, that is.)
But this has nothing to do with Ison. Like the audience watching a magician on stage, people looking at and getting stuck on Ison are having their attention directed in the wrong direction.
Don't fall for it. Your intelligence, ability and awareness is needed on real problems -- and there are PLENTY of those.

Great hybrid thread running here, I appreciate a polite discussion with no insults to those with open minds aware of disinformation of disinformation webs, If I was about to take myself my family and friends down a rabbit bunker, sure would be under the guise of solar flare CME Blackout exercise so no one knows whats happening or which hole I go down. now with all the lights out should be a fabulous opportunity for star gazers to see that comet, does anyone know if it will be a moonless night when the exercise takes place? Will they even switch the lights off? I also wonder if Denver airport tunnels had a drenching in the floods?
The denver airport mural with the cresent moon and star(comet?) wounded child, just called my gray matter- remember "In plain sight"!
http://thechive.com/2012/03/08/something-is-rotten-in-the-denver-airport-25-photos/ The guy infront of the first picture- is that the twin towers over his left shoulder? I know getting off topic you cry- maybe but sometimes it's the blurring of the edges that the clues come from.

Transcript of the mod's Skype chat yesterday. I'd returned from several hours away to find quite the earnest untangling of a great mystery going on in the mods running Skype chat. Here's the transcript:
Bill: Hi, All! I will confess and explain :)
Bill: All mea culpa.
Paul: ? :)
Bill: sheme’s thread was just her single post. The title was “Exactly what is on its way?" -- and cited three YouTube videos.
Bill: I assumed it was connected with Jiminii's “event” -- and merged the threads.
Bill: THEN -- I realized I was wrong, and it was COMET ISON that was on its way.
Paul: ahem
Bill: I no longer had a thread to re-merge, so I just moved the single POST.
Bill: Does that explain anything?
Paul: ah - that's why the yellow link to her former thread pointed to Jiminii's thread
Bill: Right.
Bill: But I have no idea why Jim's thread 'disappeared' -- if it did.
Paul: which led Christian to try to merge the yellow link in with the COMET ISON thread.
Paul: which our forum software took to mean merge Jiminii's thread with the ISON thread
Paul: which merge Christian has now fortunately reversed
Bill: That's all I know. :)
Bill: Sorry!!
Bill: Is that all untangled now?
Paul: Jiminii's thread disappeared because Christian merged the (rather broken by now) yellow link to her original thread into the COMET ISON thread
Paul: Merging a yellow link apparently tells the forum software to merge the thread pointed to by that link
Paul: Yes, all untangled now
Bill: Thank you!
Paul: :)

-------
Mods Skype chat continued (just now):
Paul: That was only half the story ... then Christian got involved, and dug the hole a little bit deeper, before getting on top of it all and fixing it up
Bill: I sort of intuited that!
Paul: Thanks to Christian, we now know that it is a really BAD idea to merge a yellow link :D
Bill: :)
Bill: It leaves the average member thinking "Thank God for Paul, because he's clearly the only mod on regular duty who knows what he's doing."
Paul: :)
Bill: While everyone else is exposed as being a bunch of amiable, well-intentioned bumbleheads who are nice people nonetheless.
Paul: :)
Bill: So everyone wins (including sheme). :)
This has all now given me a brilliant idea: that we open up the mods Skype chat to 24/7 membership audience subscription for the giveaway rate of $500 per month. We make all participants sign an NDA, and all the mods get rich through their improvised Avalon version of Yes, Minister. (Classic and brilliant UK sitcom where the Government Minister believes he's actually in charge of everything but it's really the Civil Service that actually runs rings around him.)

I know you say this is just a comet, but for me I have been getting many downloads about this comet. For some reason it has a HUGE significance to my spiritual path. I have a feeling this is the case for many people. It almost feels like a beacon or a message. It also corresponds with a year long ritual my higher self has had me do from last October to this October, which ends in six weeks. I was told that if I did not complete this ritual I would be very disappointed when my higher self comes back in a year. I have listened to everything it has asked. I get this overwhelming sense that this comet is somehow a trigger or key that unlocks something in my path or being. I also do not think that this is a spaceship, but I do think its a sign or a beacon of sorts for many people here.
In divine friendship,

I must agree. Seen it happen too often.
Major crisis occurs, a monkey wrench fell into the works...
Then suddenly the solution arrives out of nowhere,
and it becomes obvious that the monkey wrench was dropped there on purpose,
By an invisible hand,
as if to give everyone a chance to prove they can fish it out
without killing one another or tearing their own hair out.
So if this can be done in the miniature world of Avalon,
then it can also be done on the bigger stage of the earth.
Micro and macro running parallel.
So is it true about the Syria stalemate, and even peace talks?

It's a very tiny object (just three miles across at the most), and the nearest it will ever come to the Earth is 40 million miles. That's half the distance between the Earth and the sun, and 160 times the distance between the Earth and the Moon.
Saying that Ison could affect the Earth is like saying that your car on the freeway could be affected by a speck of dust in a field about 20 miles away.
:)
Edit to add: the above was a guess. I just did the math. It's actually a grain of sand (about a twentieth of an inch across, relative to the Earth as a 15 foot car) -- about 15 miles away. Go figure!

That's almost certainly because you accidentally entered your reply text within the quote, rather than at the end of it. So the software thought you'd edited the quote but not actually added your own text to make a reply.
If you look closely at your post above you'll see that the quote formatting is all tangled up, with your post and marlowe's post getting amalgamated together. If you preview your post before actually submitting it, you can catch these things before they happen.
And if you've already posted something that doesn't look quite right, you can always go back and edit/correct it as many times as you like until your post says exactly what you want it to.

what do you think of Marlowes film?
'Planet X' (whatever it is, probably a brown dwarf binary companion to our sun) is out there somewhere, and it may cause us some problems in a few years' time. (Exactly as Bob Dean says. I was there in that interview!)
But 'Planet X' has nothing whatsoever to do with Comet Ison.
(By the way there's no "rock in Cornwall where the sea level varies by 494 feet". I know Cornwall very well. The highest tides in the world are in the Bay of Fundy, Nova Scotia, which are about 50 feet or so.
I'm aware that classified Navy maps exist that show what an altered coastline might look like in the event of some giant future cataclysm. These things are not impossible to happen, and have happened before. If the US military take these things seriously, then so should we. But, again, none of this is to do with Ison.)

Comet ISON in motion (http://spaceweather.com/gallery/indiv_upload.php?upload_id=86998): At the moment ISON is still far away and faint, but its sunward velocity is impressive--more than 72,000 mph on Sept. 22nd. On Oct. 1st it will fly past the Red Planet at a distance on only 0.07 AU. Mars satellites and rovers are in position to snap the first close-up pictures of the comet.

Spacecraft army gears up to watch rare sun-diving comet
from: http://www.newscientist.com/article/dn24241#.UkAO-9LIZHU
http://blogs.discovermagazine.com/d-brief/files/2013/04/comet-ison.jpg
Once hailed as the "comet of the century", ISON is now looking like a dud for casual skywatchers. But that won't stop an army of spacecraft gathering to watch as the comet begins its dive toward the sun this week. This is a rare opportunity to glimpse a four-billion-year-old sample of the primordial solar system.
The preparations come just as NASA has pronounced dead its most famous comet-watching spacecraft, Deep Impact.
When Comet ISON was discovered last year, it was so bright that some thought it would outshine the moon. But it hasn't brightened as much as predicted. Its early outbursts, originally thought to herald a huge comet, were instead carbon dioxide frost evaporating from a metre-thick coating it collected in the solar system's frigid outer reaches.
Those warning flares were a boon to astronomy.
"We have never discovered a comet that gets this close to the sun this far out before," says Carl Hergenrother at the University of Arizona. The early warning gave astronomers enough time to plan a comprehensive observing campaign, which is rarely possible for sun-grazing comets.
Solar system sentinels
The first close-up of ISON will come on 1 October, when it flies within 10 million kilometres of the Red Planet. "Mars has the best seat in the solar system," says Carey Lisse of the Johns Hopkins University Applied Physics Laboratory. The HiRISE telescope on NASA's Mars Reconnaissance Orbiter will snap sharp pictures on a par with Hubble's images. The European Space Agency's Mars Express will also watch, alongside NASA's Curiosity and Opportunity rovers.
Around the same time, the first balloon mission to study a new-found comet will gaze up from Earth. The Balloon Rapid Response for ISON mission will launch from New Mexico in late September to measure water vapour and carbon dioxide emitted from the comet. "No other spacecraft can make these measurements," says Andy Cheng, also at the Johns Hopkins University Applied Physics Lab.
The Messenger spacecraft will spectate from its orbit around Mercury in October, and a suite of solar space-telescopes will track the comet's passage closest to the sun on 28 November. Hubble and large ground-based telescopes will observe when the comet is further from the sun.
Unfortunately, NASA's Deep Impact won't join in the festivities. The craft, which made a close-up investigation of comet Tempel 1 in 2005, made early observations of ISON in 2012. Last month, NASA lost contact with it, and they officially declared it lost today.
Dusty fireworks
Still, the combined observations of ground and space-based telescopes will be enough to gain key insights into ISON's origin and composition.
The real fireworks will happen as the comet begins to boil. When it reaches perihelion – the point in its orbit when it is closest to the sun – rocks and dust on the comet's surface will vaporise, allowing astronomers to measure what it is made of.
This fiery trip will also test the comet's strength.
Astronomers are debating whether fragile ISON will survive its encounter, but science and spectacle might both benefit from a crack-up, says Timothy Spahr, director of the Minor Planet Center at the Harvard-Smithsonian Center for Astrophysics. "What would be neat is if it fractured on the way to perihelion, and we got some really good spectra of a fresh comet," he says.

It's a very tiny object (just three miles across at the most), and the nearest it will ever come to the Earth is 40 million miles. That's half the distance between the Earth and the sun, and 160 times the distance between the Earth and the Moon.
Saying that Ison could affect the Earth is like saying that your car on the freeway could be affected by a speck of dust in a field about 20 miles away.
:)
Edit to add: the above was a guess. I just did the math. It's actually a grain of sand (about a twentieth of an inch across, relative to the Earth as a 15 foot car) -- about 15 miles away. Go figure!
.
It may be far from earth on its pass,but look how close to mars it is coming in.
Not trying to make Ison more then it is ,but if it was an ancient ancestor coming
back for a visit,Mars could be high on the visit list.:cool:

In reality that was a coincidence . At the time the of the observation, from the Earth observing frame of refference they were moving together. However if we look at their orbits Eros and Ison are not moving together at all.

[I](By the way there's no "rock in Cornwall where the sea level varies by 494 feet". I know Cornwall very well. The highest tides in the world are in the Bay of Fundy, Nova Scotia, which are about 50 feet or so.
I think the reference here is to the Mont-Saint-Michel in France, which like Fundy is at the back of a huge bay, which is where the big tides are seen. These are also claimed to be the world’s biggest, but at around forty feet (13 m), obviously they are not.
Mont-Saint-Michel is the number one French attraction outside of Paris and extensive work has been done recently to restore its island status (on the spring tide only) as it tends to silt up.

Comet ISON is in danger of disintegration according to new observational data conducted by the Group of Computational Physics and Astrophysics at the University of Antioquia, Colombia.
Optical observations have shown unexpected behaviour in the “light curve” of ISON, which has exhibited an almost constant brightness for nine months, unprecedented in cometary astronomy. It’s been predicted through the comparison of previously defunct comets that ISON has entered a “danger zone”.
Astronomer Ignacio Ferrin, from FACom, Universidad de Antioquia, analysed the most recent observational data of Comet ISON and has identified clear signatures of what he has called an “impending demise” of the comet.
“When I saw this signature I immediately went to my database of comet light curves, and found that two comets had also presented this signature: Comet C/1996 Q1 Tabur and comet C/2002 O4 Honig; to my surprise these two comets had vanished turning off or disintegrating,” he said.
Interestingly, a comparison between the light curves of ISON and eight previously disintegrating comets, is allowing Ferrin to predict that the object has already entered into a sort of “danger zone.”
It faces a potentially perilous future as it approaches the inner solar system and must survive estimated temperatures of 2,700°C.

Parallex Factor DEBUNKED.
His main beef seems to be with the fact that the tail still points in a consistent direction. That is exactly what you expect with parallax; it is a translation of the comet's apparent position, not a rotation. Here's an example using another image and distorting it in the same way:

1) If we accept the three images parallax explanation, why did NASA combine the images and increase the brightness?
2) They haven't done this composite image thing in the past with other comets, so why now?
NASA always stacks their images of comets from Hubble. Always. Every single picture of a comet you have ever seen from Hubble is a stacked image. They didn't "increase the brightness" either. The raw data is a high bit depth fits file, that is what a lot of people were playing with on the Hubble Legacy Archive viewer. These are 32 bit images, your monitor can only display 8 bits at a time. By default that viewer only shows the dim part of the histogram since that is where most of the interesting data is usually located in Hubble images. But they aren't "hiding" anything; working with high bit depth fits files requires sophisticated software to compress the extreme dynamic range of the images. Those of us who do astrophotography have such software and we just download the raw image data to work with it in proper software. The preview tool is just that, for quick previews. People like BPEarthwatch do not have the software or expertise to work with high bit depth FITS files properly, and so it becomes a conspiracy theory.
Like I said though, every comet picture from Hubble that you have ever seen published is stacked. And by default, every "dataset" or set of images from Hubble taken with a particular filter is automatically stacked in the archives as well, that is why there are three segments of the comet stacked together in that image. This kind of parallax has been seen in the raw image data before, but normally when they image a comet with Hubble they track the comet directly and this causes the stars to exhibit the parallax distortion rather than the comet. They stack the images in such a way as to remove anything that changes between the images (the stars) and leave only the comet in the image, so normally you don't get to see stars and galaxies in the pictures. You can go back to the archive of the raw data and download it and process it manually with the proper software designed to handle high bit depth FITS files so that you can stack it in such a way as to retain the stars (as well as all the cosmic radiation and other noise) and see the parallax effect. Here's an example I made using the raw Hubble images of P/2010 A2:
http://h.dropcanvas.com/8a671/hu4j.jpg
That is why on this occasion they did something I've not seen them do before and that is to track the stars directly and allow the comet to streak over time. In the public release processed photo they only used one picture of the comet and stacked the pictures of the stars. But in the archive the raw data is all available, and each dataset is automatically stacked to produce the "3 object image." In reality it's no different than the above example only in this case it's the comet that is streaking from picture to picture in the stack.

Sorry but I can't help it. Until this comet is on its way out, I will probably look at follow- ups until it's so apparent the guy is wrong. It's my nature. BPEarthwatch is still at it with new shots.

Well I hope all is well with you, obviously this comet is long gone and nothing but dust now, but I just wanted to demonstrate the proper way to investigate this kind of "anomaly" so that if it ever happens again with a future comet it can be understood rather than misunderstood. I have shared this information with BPEarthwatch but he has elected to censor it from his channel. I hope that if nothing else this event has been instructive on who can be trusted to provide good info and who cannot.
In any case, the proper way to evaluate these images is to determine what Hubble should have seen from its position in orbit around earth. We can actually recreate the path ISON should have taken relative to the stars in the image by determining what its equatorial coordinates should have been from Hubble's perspective over the times the images were taken. This requires accounting for the parallax induced by Hubble's constantly changing position as it orbits earth. The first thing we need are the orbital elements of earth, ISON, and Hubble. Here is a scan of a page containing the orbital elements of earth from the book "Practical Astronomy with Your Calculator" by Peter Duffett-Smith which contains the orbital elements for earth.

The elements for Hubble were saved on my computer from back when these images were taken; it is important to use elements close to the time of observation since Hubble's orbit is slowly decaying over time due to atmospheric drag. The rest is just math. First we need to find the number of days since the epoch of those elements.
The first step is to convert the date and time of when we want to know ISON's apparent position as seen from Hubble to a julian day number.
y = year
m = month
d = day (fraction of a day)
The procedure to convert this to Julian day number format is as follows:
If m = 1 or 2, subtract 1 from y and add 12 to m, otherwise y' = y and m' = m
If the date is > or = 1582 October 15 calculate:
A = the integer part of y'/100
B = 2-A+integer part of A/4
otherwise B = 0
if y' is negative calculate C = integer of ((365.25 x y')-.75)
otherwise C = integer part of (365.25 x y')
D = integer of (30.6001 x (m' + 1))
JD = B + C + D + d + 1720994.5
For calculating the position of earth relative to ISON we also want the JD for 1990.0 (which is the epoch of earth's orbital elements), which equals 2447892.5. Therefore, the days since epoch 1990.0 which we will call D
We will first calculate the position of earth at this timepoint before we do the calculations for
ISON.
Mean anomaly = 360/365.242191 * D/Tp + E - W
where
D = days since epoch 1990.0
Tp = Period
E = Longitude at epoch (1990.0)
W = Longitude of perihelion
Refer to the above scanned page for all of these values for Earth. In most cases that will give you a number greater than 360 for any date past 1991 because earth will have gone around the sun more than once, so you need to reduce it down to a value within 360 degrees using the following formula:
d = starting value (8568.4260132099 in this case)
(d/360 - integer of (d/360))*360 = d'
if d' < 0, then 360 + ((d/360 - integer of (d/360))*360) = d'
d' is the new value. This formula will be reused later on, I will simply refer to it as the "360 degree routine."
Next is the true anomaly, v. True anomaly is the angle between the real planet's position and its perihelion position. This calls for an iterative process to solve Kepler's equation (E - e*sin(E)
= M).
We start by making an approximation of E = E0 = M
Find the value of
sigma = E-e*sin(E-M)
where
M = mean anomaly
e = eccentricity
if sigma < 10^-6 radians then take the present value of E as the correct solution, otherwise continue for another iteration
For the next iteration find delta E = sigma/(1-e*cos(E0))
E1 = E0 - delta E
Substitute E1 back in the equation above to find a new value for sigma and repeat this routine as necessary until convering on a solution where sigma < 10^-6 radians.
tan (v/2) = Sqrt((1+e)/(1-e))*tan(E)
where
v = true anomaly
e = eccentricity
E = solution to kepler's equation from the iterative process above
find tan(v/2), take the arctangent and multiply the result by 2. You need to evaluate the numerator and denominator within the arctan function separately in order to do a quadrant disambiguation routine. If the numerator is positive and the denominator negative, add 180 to the result of the arctan function (after converting the result to degrees of course). If the numerator is negative and the denominator positive, then add 360 to the arctan result unless that makes it greater than 360 degrees, in which case add 180 degrees. Finally, if both the numerator and denominator are negative, then add 180 degrees to the result of the arctan function. Otherwise if you have made no other additions and the result is negative, add 180 degrees, or else keep the result of the arctan function without adding or subtracting anything.
Now you have v, the true anomaly.
Now we need to calculate heliocentric longitude, l.
l = (360/365.242191 * D/Tp) + 360/pi * e * sin(360/365.242191 * D/Tp + E - W)
where
D = days since epoch
Tp = Period
e = eccentricity
E = longitude at epoch
W = longitude of the perihelion
Use the 360 degrees routine to get l within 360 degrees.
Now we need the radius vector, that is to say, distance from the sun, r.
r = (a*(1-e^2))/(1+e*cos(v))
where
a = semi-major axis of the orbit
e = eccentricity
v = true anomaly
Now we repeat these calculations for Hubble given the values for Hubble's orbit above.
For Hubble we're dealing with an inclined orbit, so we also need to find the latitude. This is given by
U = Arcsin(sin(L - Omega)*sin(i))
where
L = true longitude of Hubble (same formula as heliocentric longitude for earth)
omega = longitude of the ascending node
i = inclination
Now we need to find the geocentric longitude; true longitude consists partly of values which are inclined to the equator by Hubble's inclination.
L' = v+w'-O
where
v = true anomaly
w' = longitude of perigee
O = argument of perigee
Perform the 360 degree routine on L'
Now we re-orient L' back into the plane of the equator so that we can find the geocentric longitude with respect to the vernal equinox, effectively geocentric right ascension.
geocentric right ascension = arctan((sin(L')*cos(e))/cos(L'))+O
where L' equals the result from above
e = eccentricity
O = argument of perigee
Remember to evaluate the arctan function using the quadrant disambiguation routine described above
Now we need to find the geocentric longitude. We now know the angle of Hubble east of the vernal equinox, but we need to know the number of degrees the vernal equinox is of the 0 line of longitude, the prime meridian, in other words, we need to know Greenwhich mean sidereal time.
GMST = 18.697374558+24.0657098244191*(JD-2451545)
GMST*15 = GMST in degrees
Perform the 360 degree routine on GMST in degrees to get the value within 360 degrees.
Now take the geocentric right ascension and subtract GMST in degrees. This is the eastern
longitude of Hubble. If the value is negative, it's west longitude, if the value is positive it is east longitude. Save this value and the latitude calculated above for later.
Now we need to calculate the position of ISON relative to earth. The orbital elements are listed above. We will approximate ISON's orbit as a parabolic orbit to aid in the ease of calculation.
First find W
W = (0.0364911624/(q*sqrt(q))) * d
where
q = perihelion distance
d = days since perihelion (perihelion date in Julian Days - JD)
Now we need to solve s^3 + 3s - W = 0
First approximate s = s0 = W/3
calculate sigma
sigma = s0^3 +3*s0 - W
if sigma < 10^-6 degrees then take s as the correct value otherwise continue with the iterations and proceed below
s1= (2*s0^3 + W)/(3(s0^2 + 1))
substitute s1 back into the formula above to find sigma and repeat until the value is within the accuracy of sigma <10^-6 degrees. Then take that value of s and proceed
Find the true anomaly
v = 2*arctan (s)
Find the distance from the sun
r = q*(1+s^2)
where
q = perihelion distance in AU
find heliocentric ecliptic longitude
l = v+w'
where
v = true anomaly
w'= longitude of perihelion
find the heliocentric ecliptic latitude
U = Arcsin(sin(l - O)*sin(i))
where
l = heliocentric ecliptic longitude
O = argument of perihelion
i = inclination
Now we need l' which is the heliocentric longitude projected onto the plane of the ecliptic.
l' = arctan((sin(l-O)*cos(i))/cos(l-O))+O
where
l = heliocentric ecliptic longitude
O = argument of perihelion
i = inclination
remember to perform the quadrant disambiguation routine on the arctan function
Now we calculate the geocentric ecliptic longitude (lam) and latitude (beta) of comet ISON. If ISON's radius vector from the sun is less than earth's at the time you are evaluating you can regard it as an inner planet in which case the formula is this:
lam = 180 + Le + arctan ((ri*sin(Le-l'))/(re-ri*sin(Le-l')))
where
Le = heliocentric longitude of earth
re = radius vector of earth
rI = radius vector of ISON
l' = heliocentric longitude of ISON projected onto ecliptic
Note that you need to follow the same quadrant disambiguation routine as listed above for the arctan function in this formula.
If ISON's radius vector from the sun is greater than earth's at the time you are evaluating you can regard it as an outer planet in which case the formula is this:
lam = arctan((re*sin(l'-Le)/(rI-re*cos(l'-Le)))+l'
where
Le = heliocentric longitude of earth
re = radius vector of earth
rI = radius vector of ISON
l' = heliocentric longitude of ISON projected onto ecliptic
Note that you need to follow the same quadrant disambiguation routine as listed above for the arctan function in this formula.
beta is calculated with the following formula:
beta = arctan((r'*tan(U)*sin(lam-l'))/(re*sin(l'-Le))
where
Le = heliocentric longitude of earth
re = radius vector of earth
l' = heliocentric longitude of ISON projected onto ecliptic
U = heliocentric latitude for ISON
r'= radius vector of ISON
Note that you need to follow the same quadrant disambiguation routine as listed above for the arctan function in this formula.
Distance of ISON from earth
reI=sqrt(rI^2+re^2-2*re*ri*cos(l'-Le)*cos(U))
where
Le = heliocentric longitude of earth
re = radius vector of earth
rI = radius vector of ISON
l' = heliocentric longitude of ISON projected onto ecliptic
U = heliocentric latitude for ISON
For the next step we will need the obliquity of the ecliptic. This can be calculated with the following formula, which will need time "t" centuries from 2000.0. We can calculate t thusly:
t = ((JD-2451545)/36525)
where JD = julian day number
Obliquity of the ecliptic (Obl) can then be calculated with this formula:
Obl = 23.43928-0.013*t+0.555*(10^-6)*(t^3)-0.0141*(10^-8)*(t^4)
Now we just have to convert these coordinates from ecliptic to equatorial and we will have the geocentric equatorial coordinates of ISON at this timepoint.
Right ascension = arctan((sin(lam)*cos(Obl)-tan(beta)*sin(Obl))/cos(lam))
where
lam = geocentric ecliptic longitude
beta = geocentric ecliptic latitude
obl = obliquity of the ecliptic
Note that you need to follow the same quadrant disambiguation routine as listed above for the arctan function in this formula.
declination = arcsin(sin(beta)*cos(obl)+cos(beta)*sin(obl)*sin(lam))
where
lam = geocentric ecliptic longitude
beta = geocentric ecliptic latitude
obl = obliquity of the ecliptic
Now we have the geocentric coordinates for ISON, but we need to account for the parallax induced by Hubble's orbit.
First find u
u = atan(0.996647*tan(U))
where U = geocentric latitude of Hubble
Next find p*sin(theta')
p*sin(theta') = 0.996647*sin(u)+(r/6378140)*sin(theta)
where
u = u above
r = altitude of hubble (convert to meters)
theta = geocentric lattitude of hubble
find p*cos(theta')
p*cos(theta') = cos(u)+r/6378140*cos(theta)
where
u = u above
r = altitude of hubble (convert to meters)
theta = geocentric lattitude of hubble
pi = (atan((6378140+r)/149597870700)*3600)/reI)/3600
where
r = altitude of Hubble (in meters)
reI = distance of ISON from earth
LST = (GMST*15)+Lh
where
GMST = Greenwhich mean sidereal time
Lh = geocentric longitude of Hubble
Perform the 360 degree routine to get LST in degrees for the equation below
delta RA = atan((p*cos(theta')*sin(pi)*sin(LST-RA))/(cos(declination)-p*sin(theta')*sin(pi)*cos(LST-RA))
where
RA = geocentric right ascension of ISON declination = geocentric declination of ISON.
Note that you need to follow the same quadrant disambiguation routine as listed above for the arctan function in this formula.
subtract delta RA from the geocentric right ascension of ISON to get the parallax corrected right ascension of ISON which we will call the hubble centric RA
gamma = atan(tan(p*sin(theta')/p*cos(theta'))*cos(.5*delta RA)*(1/cos(LST-.5*(geocentric RA + hubble centric RA)))
delta declination = (p*sin(theta')*sin(pi)*sin(gamma-geocentric declination))/(sin(gamma)-p*sin(theta')*sin(pi)*cos(gamma-geocentric declination))
subtract delta declination from the geocentric declination to get the parallax corrected declination of ISON which we will call the hubble centric declination. Now we have both the hubble centric RA and hubble centric declination for this point in time. If you repeat these equations over multiple points in time covering the imaging times for the Hubble images you can generate a list of coordinates for ISON over the imaging session and graph the predicted trail of ISON as seen from Hubble over that period of time. Doing so results in the following graph which matches with the images taken by Hubble:

@ astronomylive — thank you, and welcome to the forum!
Yes, Ison was always just a comet, as Elenin was. And 'was' is the operative word, as it definitely isn't a comet any more. :)
I posted the parallax information myself quite a while back, either on this thread or another (there were several, I believe!). The problem, as always, is a number of YouTube channels whose enthusiasm is greater than their scientific understanding. (That includes BPEarthwatch, which categorically, despite a grand-sounding name, is NOT a good source of information.)

I like that! A very diplomatic and non-judgemental phrase. I shall try to remember it.

If Bill is not get upset , I could even use it more often than him. Some times I can not find soft words, to wake others, then my silence encourage them to talk more.

Unprecedented stuff going on here...
The thread about the comet outlived the comet itself! :)

And we have a returning comet of our own - great to see you back Raf :)

It seemed to provide a teachable moment. Even after a couple of my videos about parallax were cited by NASA I was still getting responses demanding to "see the math." I was quite busy at the time actually tracking the comet and just never got around to it, finally I had a weekend where I could focus on it. Hubble is revisiting a lot of old objects for its 25th anniversary in space, so I was inspired to join in the fun by revisiting an old comet.
