Coronal mass ejection — 2026-10-05 07:48 UTC
Wide CME observed to the NE in SOHO LASCO C2/C3 and GOES CCOR-1, and to the NW in STEREO A COR2. The source is a far-sided filament eruption over the NE limb, observed in SDO AIA 171/193/304 as field line movement, EUV wave, and filament ejecta starting around 2026-10-05T07:18Z, although these features are better observed in the wider field-of-view in GOES SUVI 171/193/284/304. Also observed weakly in STEREO A EUVI over its NW limb starting in EUVI 304 as filament ejecta around 2026-10-05T06:45Z and in EUVI 195 as field line movement around 2026-10-05T07:25Z.
