Coronal mass ejection — 2026-10-09 00:45 UTC
CME faintly seen to the east in GOES CCOR-1 imagery. There is a data gap in SOHO LASCO C2/C3 imagery starting at 2026-10-09T00:48Z and a data gap starting in STEREO A COR2 at 2026-10-09T00:53Z. The source is likely beyond the E limb as seen in available EUV imagery, as slow moving field lines are visible on the E limb in SDO AIA 193 and GOES SUVI 284 imagery starting as early as 2026-10-08T18:30Z.
