Coronal mass ejection — 2026-10-09 07:15 UTC
CME seen to the NW in GOES CCOR-1 imagery. There is a data gap in SOHO LASCO C2/C3 and STEREO A COR2 at the time of this CME. The potential source is unclear, but is likely an eruption from AR 14547 (approximately N15W90) starting around 2026-10-09T06:30Z, best seen as moving/opening field lines in SDO AIA 193 and GOES SUVI 284 imagery.
