Coronal mass ejection — 2026-11-07 09:36 UTC
First in a pair of far-sided CMEs from a filament eruption, followed by slower CME 2026-11-07T10:24Z. This leading edge is more faint and observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source for both is a far-sided filament eruption, observed well in GOES SUVI 284/304 over the N limb starting around 2026-11-07T08:04Z, with the filament first lifting off as early as 2026-11-07T06:51Z. Also observed to the NW in STEREO A EUVI 195 as field line movement around 2026-11-07T08:35Z and STEREO A EUVI 304 as filament ejecta around 2026-11-07T06:15Z.
