Note: This CME is visible to the southeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is an eruption observed near the southeast limb starting around 2026-03-27T00:40Z as seen in GOES SUVI 131/171/195/294/304 imagery. An opening of field lines can be seen over the southeast limb at this time in GOES SUVI 171/195/284 imagery and post-eruptive arcades are visible on the southeast limb starting around 2026-03-27T01:00Z in GOES SUVI 131/171/195/304 imagery.
