Coronal mass ejection — 2026-11-12 21:12 UTC
Faint CME seen to NNW in early SOHO LASCO C2 coronagraph imagery and very faintly in early timestamps of GOES CCOR-1 but completely covered by an evening data gap in STEREO A COR2 coronagraph. Its source is most likely a faint prominence seen erupting on/behind the NNW limb starting at 2026-11-12T21:13Z, as seen to the NNW in GOES SUVI 304. Unfortunately, the source cannot be seen in STEREO A EUV imagery, since it is covered by the above mentioned data gap in STEREO A.
