Coronal mass ejection — 2026-10-11 23:15 UTC
This CME is visible to the southwest in GOES CCOR-1 and SOHO LASCO C2/C3 imagery. This event is not seen in STEREO A COR2 in real-time due to a data gap starting at 2026-10-11T17:38Z. The source may be related to dimming centered near S20E30 starting around 2026-10-11T22:00Z as seen in SDO AIA 193 and GOES SUVI 195 imagery.
