Coronal mass ejection — 2026-11-09 09:12 UTC
Faint CME observed to the NE in SOHO LASCO C2, and faintly in SOHO LASCO C3 and GOES CCOR-1, not observed in STEREO A COR2. The source may be faint field line movement on or slightly beyond the NE limb in GOES SUVI 171 around 2026-11-09T07:06Z. This front is followed by a faint, slow, wide structure measuring approximately 122 km/s plane-of-sky, which may also be related to this eruption or separate far-sided, without current STEREO A COR2 to help differentiate.
