Coronal mass ejection — 2026-11-06 16:15 UTC
Wide CME visible to the NW in GOES CCOR-1 and SOHO LASCO C2/C3 imagery. The CME is not visible in STEREO A COR2 imagery in real-time due to a data gap starting at 2026-11-06T13:38Z. The likely source is a filament eruption that starts to lift off in STEREO A EUV 304 imagery, around N35W140, starting at 2026-11-06T13:15Z. The filament can also be seen lifting off beyond the west limb in GOES SUVI 304 imagery. Moving/opening field lines are also visible in SDO AIA 171 in ISWA, SDO AIA 193, and GOES SUVI 284 imagery.
