Note: This CME is visible to the northwest in SOHO LASCO C2/C3, GOES CCOR-1 (partially obscured by the pylon), and STEREO A COR2 imagery. The source is a slow-to-lift-off filament eruption visible over the northwest limb in SDO AIA 171/304 and GOES SUVI 171/284/304 imagery starting around 2026-09-06T22:00Z. This same filament is visible lifting off north of disk center as seen in STEREO A EUVI 195/304 imagery.
