    We "oldies" here at Avalon have named it "Santa"..... used to show up a lot in the Lasco picts...haven't seen it in a while.

    NO idea what it is, but it isn't the "Winged Planet" as far as I know..... i don't think it is a planet at all.....maybe a "space critter" of some sort.

    From spaceweather.com:

    Quote FOUR CMEs: On Sept. 19th, the STEREO-SOHO fleet of spacecraft surrounding the sun detected six coronal mass ejections (CMEs). Two of the clouds rapidly dissipated. The remaining four, however, are still intact and billowing through the inner solar system. Click to view a movie of their forecasted paths:



    According to analysts at the Goddard Space Weather Lab, who prepared the movie, one CME should hit Mercury on Sept. 20th at 05:40 UT while another delivers a glancing blow to Earth's magnetic field on Sept. 22th at 23:00 UT. All impact times have an uncertainty of plus or minus 7 hrs.

    High-latitude sky watchers (on Earth) should be alert for auroras when the CME arrives.
    And this is truely a "Heads UP!" Alert:

    Quote RE-ENTRY ALERT: NASA reports that UARS, an atmospheric research satellite the size of a small bus, will re-enter Earth's atmosphere on Sept. 23rd plus or minus one day. The disintegration is expected to produce a fireball that could be visible even in broad daylight. Not all of the spacecraft will burn up in the atmosphere, however; according to a NASA risk assessment, as many as 26 potentially hazardous pieces of debris could be scattered along a ground track some 500 miles long. But where? No one can say. Because of the rapid evolution of UARS's decaying orbit, the location of the debris zone is not yet known. Stay tuned for improved predictions as the moment of re-entry nears.

    G'day All,

    According to iSWA (one of NASA's really nifty web based toolsets) a number of small CME's were detected by STEREO on 19-09-2011 at 21:30 UT.
    There appears to be a possibility of one glancing the Earth's magnetosphere with an estimated arrival of 21-09-2011 23:00 according to NASA (a day earlier than Spaceweather is saying, reckon someone did a typo).
    Estmated Magnetopause standoff distance: 5.7Re.

    Solar Forecast from IPS Australia (Last updated 19 Sep 2011 23:30 UT) states that there are no expected risks of increased activity.

    The forecast goes on:
    Quote COMMENT: There were a number of C-class flares, the largest being
    a C6.9 at 1541 UT from region 1301 (N20E63). There were also
    a number of CMEs, only one of which appears to have a weak, Earth
    directed component, based on the STEREO images. This CME appears
    to have originated from region 1301 before 0654 UT and may be
    geo-effective around 23 Sep. Solar wind parameters have been
    undisturbed over the past 24 hours and are expected to remain
    so over the forecast period.
    As MorningSong mentioned: Space Weather also reports that one of the CME's may glance the Earth's magnetosphere and the image from Goddard shows this [see MorningSong's post above].

    New arrival and yet unnumbered sunspot on the eastern rim of the Sun sent off an X-class flare, 1.4 mag, this morning around 10:30 UTC. It probably will not be geoeffective.

    Just one half hour before, sunspot 1295 let off a M-class flare, mag 1.1, as well as a C6.6 at 4:20 UTC. The region numbered N15E88 released a C 8.9 at 9:09 UTC.

    This is what happens when a geomagnetic storm arrives.

    Aurora from space!

    During the geomagnetic storm last weekend those lucky enough to be at high latitudes were not the only ones to catch the resulting aurora. Astronauts on the International Space Station got a spectacular view from ABOVE the aurora! This footage was recorded over the southern Indian Ocean over a 23-minute period from 17:22:27 to 17:45:12 GMT on Sept. 17.

    G'day All,

    Here's the latest info on the other days X 1.4 and associated CME from IPS Oz:
    Background X-ray flux remained mostly at low C-class levels. Newly assigned region 1302 (N13E75) produced an M1.1 flare at 1000 UT and an X1.4 flare at 1101 UT. Region 1295 (N23W61) flared at C6.6 level. Region 1302 shows two large spots at this time and is considered to have the potential for further X-class flares. SOHO LASCO, STEREO and SDO images show a strong CME associated with the X flare. This CME is expected to be geoeffective. Solar wind parameters were mostly undisturbed. These parameters are expected to become mildly disturbed later today, becoming disturbed in the latter part of 24 Sep due to the CME reported above, then settling over the 25 Sep.
    Space weather is reporting much the same: 'A minor glancing encounter with the outskirts of the CME is, however, possible on Sept. 25th'.

    Kind Regards,
    Panopticon

    I always seem to be one step behind the bots, but here goes:

    New X-class Mag 1.9 flare this morning around 9:21 UC from sunspot 1302 on the NE limb.



    R3 (strong) radiation emission, Type II and Type IV Radio Emission detected, Proton 10MeV Integral Flux above 10pfu expected.

    The Proton flux >100pfu (S2 level) (into Earth's atmosphere) continues to increase since the X flare on Sept 22nd.

    G'day All,

    Just to add to Morning Songs report.

    IPS Oz Space Weather Forecast:
    Quote There were a number of flares over the period; most notably an X1.9 at 0940UT, an M7.1 at 1320UT, an M2.8 at1815 UT and an M3.0 at 1921UT (AR 1302(N12E47)), an M3.1 at 18725UT from AR1295 (N24W78) and an M5.8 from new AR1303 (S28W60). LASCO and STEREO images show a weak CME associated with the X1.9 flare and a strong CME associated with the M7.1 flare, which is expected to be geoeffective about 26-27 Sep. Solar wind parameters were undisturbed over the reporting period (the expected disturbance did not occur). Solar wind parameters are expected to become disturbed on 26 Sep. Previous X-flare producing region 1283 is due for return to the north-east limb around 25 Sep.

    As you can see on the 3-day GOES X-ray Flux Monitor, we have had quite a few M-class flares in the past 2 days ( 11 and counting) since the X1.9 on the 24th. Things are really heating up with the new sunspot 1302!

    SolarMonitor.org notes that the most likely region to flare is 1302.
    Probabiliy: X flares (19%) M flares (50%) C flares (53%)



    Here's the latest from spaceweather.com:

    Quote STRONG SOLAR ACTIVITY: On Saturday morning, Sept. 24th, behemoth sunspot 1302 unleashed another strong flare--an X1.9-category blast at 0940 UT. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:



    The movie also shows a shadowy shock wave racing away from the blast site. This is a sign that the blast produced a coronal mass ejection (CME). Analysts at the Goddard Space Weather Lab say the CME could deliver a glancing blow to Earth's magnetic field on Sept. 26 at 14:10 UT (+/- 7 hours); click here for an animated forecast track. Geomagnetic storms are possible when the CME arrives.

    SOLAR STATIC: Active sunspot 1302 has turned the sun into a shortwave radio transmitter. Shock waves rippling from the sunspot's exploding magnetic canopy excite plasma oscillations in the sun's atmosphere. The result is bursts of static that may be heard in the loudspeakers of shortwave radios on Earth. Amateur radio astronomer Thomas Ashcraft recorded this sample from his backyard observatory in New Mexico on Sept. 24th:



    "Saturday was a super-strong solar day with near continuous flaring and radio sweeps," says Ashcraft. "The sound file (above) corresponds to an M3 flare at 1918 UTC. It was the strongest radio sweep of the observing day."

    "Try listening to the radio bursts in stereo," he advises. "I was recording on two separate radios at 21.1 MHz and 21.9 MHz, and I put each one into its own channel of the audio file. This gives a spatial dimension as the bursts sweep down in frequency."

    The Mag field looks like it disappeared this morning! Like the tide rushing out to sea before a tsumani....



    The "glancing blow" predicted from a CME on the 24th has reached Earth today around 12:30 UTC:



    Pressure from the huge wave of solar radiation pushed our magnetosphere (bow shock) well beyond the geosynchronous orbit (where many sats are suspended):

    G'day MorningSong,

    It's been a pretty impressive week this week as far as the solar flare and cme's go!
    The IPS Magnetopause Model is not as pretty as the others (nor does it have the bells and whistles) but shows the boundary, solar wind speed, bz, standoff distance and geo-syn (with some sats) clearly.
    Unfortunately (or is that fortunately) it's java based so I can't embed it here.
    It's the second thing I have a look at in the morning (first being their space weather page) as it's no non-sense and quick loading.

    Kind Regards,

    Update on spaceweather.com confirmes my previous posts:

    Quote GEOMAGNETIC STORM: A strong-to-severe geomagnetic storm is in progress following the impact of a coronal mass ejection (CME) at approximately 12:15 UT on Sept. 26th. The Goddard Space Weather Lab reports a "strong compression of Earth's magnetosphere. Simulations indicate that solar wind plasma [has penetrated] close to geosynchronous orbit starting at 13:00UT." Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields. High-latitude sky watchers should be alert for Northern and Southern Lights after nightfall.

    Do you ever watch any of 'solarwatcher' (also known as 'thebarcaroller') on youtube? He does a great job at explaining what's going on with the sun and how it may impact Earth (i.e. earthquakes). Here's one of his video re: the X-class flare on 9/24. He also has a website: www.solarwatcher.net, I've never been to it, but it might be worth a visit. He's great!

    Coronal Mass Ejection (CME) hits Earth's Magnetosphere Today, Causes Ground Currents In Norway

    A coronal mass ejection (CME) hit Earth's magnetic field at approximately 12:15 UT on Sept. 26th. The impact caused significant ground currents in Norway. Also, the Goddard Space Weather Lab reports a "strong compression of Earth's magnetosphere. Simulations indicate that solar wind plasma [has penetrated] close to geosynchronous orbit starting at 13:00UT." Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields.

    Sept.26 2011,at 12.36 UTC a magnificent shockwave from a CME arrived in our atmosphere,with an effect on all of my instruments.The shockwave passed the ACE satellite at 11.52 UTC,just 44 minutes earlier.

    Stay tuned for updates. Aurora alerts: text, voice.
