Coronal mass ejection — 2026-11-13 03:24 UTC
This CME is faintly visible to the NE in STEREO A COR2 and SOHO LASCO C2/C3. The CME is not seen in GOES CCOR-1 due to Earthshine starting 2026-11-13T03:45Z. The potential source may be an eruption with a small region of dimming and post-eruption arcades starting at 2026-11-13T00:21Z as best seen in SDO AIA 193 imagery from Active Region 14575 (S09E50).
