Coronal mass ejection — 2026-11-09 18:15 UTC
Faint, narrow CME observed to the W only in GOES CCOR-1, due to a real-time data gap in SOHO LASCO C2/C3 and STEREO A COR2. The source is likely an eruption from AR 14571 starting around 2026-11-09T15:57Z, observed as dimming and brightening in SDO AIA 193 and field line movement in SDO AIA 171.
