Coronal mass ejection — 2026-10-02 08:24 UTC
CME visible to the NW in SOHO LASCO C2/C3 and GOES CCOR-1. The CME overlaps in the field of view with the CME first seen in STEREO A COR2 at 2026-10-02T00:53Z. The CME may potentially be faintly seen to the NNE in STEREO A COR2. The potential source may be AR 14535, located around N11W75, with a small region of brightening and moving field lines best seen in SDO AIA 193 imagery starting at 2026-10-02T05:52Z.
