Coronal mass ejection — 2026-10-08 16:24 UTC
CME visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1 as well as possibly faintly to the east in STEREO A COR2. This CME overlaps in the field of view with the CME first seen in STEREO A COR2 at 2026-10-08T16:53Z. The potential source is a filament eruption centered around N05W25 as best seen in SDO AIA 193/304 imagery. The eruption is best seen as dimming starting at 2026-10-08T09:21Z in SDO AIA 193. The filament liftoff can be best seen from the point of view of STEREO A EUV 195/304, in the NE quadrant from the point of view of STEREO A.
