CME 2021-11-24 14:00 SE Quadrant

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.

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.

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.
