Note: CME seen to the north in SOHO LASCO C2/C3 and GOES CCOR-1. Not seen in STEREO A COR2 due to a data gap from 2026-03-02T16:23Z to 2026-03-03T04:09Z. The potential source eruption is seen in GOES SUVI 195 imagery around N25W20, north of AR 14383, starting at 2026-03-02T22:24Z as dimming and post-eruptive arcades.
