Note: Minor CME seen to the northwest in GOES/CCOR-1 and SOHO/C2 and SOHO/C3 coronagraphs and due north in STEREO A/COR2 in association with a minor eruption in AR 4419 (~W52) starting around 2026-04-23T22:45Z. The eruption is seen best in GOES SUVI 284 as a brightening and the expulsion of plasma to the northeast.
