Coronal mass ejection — 2026-10-29 10:36 UTC
This CME is visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1 and to the east in STEREO A COR2 imagery. The source is a filament eruption with liftoff starting around 2026-10-29T07:36Z seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 195/304 imagery. The footpoints extend from about S20W20 to S10W50. Post eruptive dimming is visible in SDO AIA 193 with an opening of field lines seen over the southwest limb in SDO AIA 171 and GOES SUVI 171/284 imagery.
