PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the W in STEREO A COR2 starting at 2025-08-23T02:23Z. This CME is also seen to the W in SOHO LASCO C2/C3 and GOES CCOR-1. The source of this CME is most likely far-sided. There is some eruptive activity from on/beyond the W limb best seen in STA EUVI 195 starting as early as 2025-08-22T20:35Z.
