Coronal mass ejection — 2026-11-05 20:00 UTC
CME first seen in white light imagery to the E in GOES CCOR-1 starting at 2026-11-05T20:00Z. In real time, this CME is covered by data gaps in SOHO LASCO and STEREO A COR2. The source of this CME is like related to an M3.5 class flare from AR 14566 (S08E35) which peaked at 2026-11-05T18:33Z. The flare is best seen in SDO AIA 131. Some post-eruptive dimming can also be seen in SDO AIA 193. Due to the source location being in close proximity to a coronal hole, some deflection is likely.
