Coronal mass ejection — 2026-10-24 21:48 UTC
Relatively narrow CME to the NNW seen in SOHO LASCO C2 and in GOES CCOR-1. This CME is not seen in SOHO LASCO C3 because of poor image quality. It is covered by the data gap in STEREO A COR2 so far. The source is likely the opening/movement of field lines and possibly small ejecta seen on/beyond the NW limb in SDO AIA 193/171/131/304 after 2026-10-24T21:12Z.
