Drax Spacex Posted November 24, 2021 Share Posted November 24, 2021 I'm trying to find the source on the solar disk of the CME 2021-11-24 14:00 SE Quadrant as viewed from LASCO C2. Looking at the same event on STEREO A COR2, because it erupts to the right side not the left side, it does appear to be Earth-view side, not far side. SDO imagery is uncharacteristically lagging behind LASCO imagery. So right now I can't confirm where on the solar disk this CME may have originated. Since we didn't see any X-ray flux indicating a significant solar flare, I will make an early guess that this CME could be the result of a filament eruption.

Solarflaretracker200 Posted November 25, 2021 Share Posted November 25, 2021 14:00 or 16:00? Because here I have something happening at 16:09 (I literally have no idea why I screenshot this at 16:09) Link to comment Share on other sites More sharing options...
Drax Spacex Posted November 25, 2021 Author Share Posted November 25, 2021 A device sometimes captures what it wants you to see but yes, around that time. SDO data has now filled in, and the snippet below from the latest SWPC Forecast Discussion makes mention of the CME. Indeed, the CME was due to a filament, though we only see from SDO imagery a disappearing filament not a launching filament. :Product: Forecast Discussion :Issued: 2021 Nov 25 0030 UTC ... A CME from a 5 degree filament that disappeared from GONG Ha looping images from near S34E28 was observed in NASA STEREO COR2 images starting at 24/1409 UTC. The same event is visible in a few available images of NASA SOHO LASCO C2/C3. Analysis and modeling is ongoing as imagery backfills key timeframe gaps, but initial thoughts are a glancing blow to the south on 28 Nov. ...

Sam Warfel Posted November 25, 2021 Share Posted November 25, 2021 it looked pretty non-Earth directed to me, although I am not sure exactly how much the Parker Spiral curves it Link to comment Share on other sites More sharing options...
