Coronal mass ejection — 2026-10-08 16:12 UTC
CME faintly seen to the east in SOHO LASCO C2/C3 and GOES CCOR-1. The CME may potentially be visible to the west in STEREO A COR2. The potential source for this CME may be beyond the east limb, as moving field lines are seen in SDO AIA 193 starting around 2026-10-08T09:21Z. Some ejecta of material can also be seen beyond the east limb in GOES SUVI 304 as well.
