Coronal mass ejection — 2026-11-05 21:24 UTC
CME seen to the east in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. The CME is also faintly visible to the east in STEREO A COR2 after a data gap from 2026-11-05T14:35Z to 2026-11-06T01:38Z. The potential source location may be a minor eruption seen near the SE limb in GOES SUVI 304 imagery starting around 2026-11-05T19:28Z located near S15E75. Moving/opening field lines are also best seen in SDO AIA 171/193 imagery.
