Coronal mass ejection — 2026-10-09 14:36 UTC
Faint CME with a loop front seen to the NW in the early SOHO LASCO C2 imagery, also seen faintly in C3 and GOES CCOR-1. It is fully covered by long data gap in STEREO A COR2 coronagraph. The source is the occulted (or on-limb) M1.3 flare likely from Active Region 14547 (N15W94), now decayed to a plage, which had just rotated off the visible disk before the flare. Other coronal signatures include a small ejecta seen in SDO AIA 304 at the time of the flare and movement/opening of field lines seen to the NW behind the limb in SDO AIA 171/193 and GOES SUVI 304/284.
