Coronal mass ejection — 2026-10-06 09:53 UTC
CME observed to the NE in STEREO A COR2, also faintly observed to the N in SOHO LASCO C2/C3 and GOES CCOR-1. The source is AR 14549, associated with an M1.8 class flare (N08E07) peaking at 2026-10-06T08:05Z, observed in SDO AIA 131. Also observed as field line movement, EUV wave, dimming, and brightening in SDO AIA 171/193 starting around 2026-10-06T07:52Z, with brightening and filament ejecta in SDO AIA 304. Also observed well in STEREO A EUVI 195/304 starting around 2026-10-06T08:05Z as field line movement and filament ejecta on the NE limb, with some northward deflection.
