Coronal mass ejection — 2026-10-06 06:23 UTC
Full halo CME in SOHO LASCO C2/C3 and GOES CCOR-1, first seen to the NE in STEREO A COR2 (shock fully to the E, wide). The source is AR 14549, associated with an M1.4 flare (N10E12) peaking at 2026-10-06T06:10Z, observed in SDO AIA 131. Also observed as an EUV wave, field line movement, brightening, filament ejecta, and small post-eruptive arcade in SDO AIA 131/171/193/304. Additionally observed on the NE limb of STEREO A EUVI 195 as field line movement and EUV wave, and EUVI 304 as filament ejecta.
