View Full Version : Understanding the sun

A beautiful sunny day to you all, greetings :wizard:

I was wondering if any astronomers could help me understand parts of this video:

http://sohowww.nascom.nasa.gov/data/LATEST/current_c3_combo.mpg

When I first watched it, I noticed a lot of flashing which I initially took for sun flares but when I paused the video at those exact stages I found images to be fully blotted out and covered with gray rectangles (on the right).

One of such instances is 2013/07/22 03:42.

Looking back at the blue part on the left I could see that the hue of blue indeed differed in that particular area. So it looks like another image was overlaid on the original there.

In reality I've no idea what I'm looking at. How do I understand this video correctly?

Other examples:
2013/07/24 15:54
2013/07/21 16:06
2013/07/21 22:06

Second question: what are the two shadowy circles alongside the sun in :

2013/07/21 22:18
2013/07/21 23:30
2013/07/23 06:06
2013/07/23 06:30
2013/07/24 00:54
2013/07/24 01:54
2013/07/24 04:42
2013/07/24 11:18

The timings are recurrent so it looks like whatever it is, it's constantly there.


Thirdly:
2013/07/22 03:54 is something really bizarre too. Especially compared to 2013/07/22 03:42. It almost looks like the sun briefly went out and on again.

Fourthly:
There's a broad straight ray going out from the sun and its constant too. You can see it in the lower left side of the picture.

2013/07/23 13:42
2013/07/24 01:42

Again recurrent timings. Is it a ray that always comes out on the same place in the same time, same shape?

And lastly:

2013/07/23 01:30 is a blast of an image. Amazing, beautiful.


Appreciate your help in advance.

most of this (if not all) can be simply explained thusly:

we just do not have a good way of capturing the sun, our lense based cameras cannot handle the amount of energy that hits them from the sun, we get lense flare, phantom images, and with modern sensors digital artifacts and issues happen quite often.

Yes, but in that case wouldn't the irregularities have to be more random?

not really, all lenses are basically the same design, the same shape roughly with just minor thickness differences to change the way light is focused. Digital artifacts can be pretty random, but always seem to be geometrical in shape probably just due to the nature of the firmware on the ccd sensor,

they directly blot out EMV's that are always around the sun ... the spirt energy that protects planets and sentient life from the suns harmful burst... James Horak has a great site about EMV's ...

Vessels is too much for me personally... I did see lots of those sparks in the video, though. I took them to be stars, comets, or whatever nearby bodies undergoing such heating in the close presence of the sun that they were...sent for a spark.

It makes sense that the sun is too bright for us to handle. But lens flares shouldn't appear as perfectly solid grey rectangles.

what about CCD artifacts? it's probably the same camera, maybe the sensor has some an area with a bad or failing CCD or one of the many other things that can go wrong (http://www.eso.org/~ohainaut/ccd/CCD_artifacts.html)

seems like it casts enough doubt to make me question.

I know there are many who believe NASA are hiding some scary stuff (and indeed, they may be, I'm not in a position to know), but vary large objects near the sun, 'hushed-up' anomalous solar behaviour and other large-scale astronomical shenanigans cannot be kept from the tens of thousands of well-equipped amateur astronomers all over the globe.

As has been stated on PA before, NASA does not have a monopoly on all forms of astronomical observations.
