FLR: Flare
OFL: Moving/Opening field lines
BR: Brightening
EUVW: EUV Wave
Morphology Keyword:
O: Other
Note: CME initially seen to the NW in SOHO LASCO C2 and STEREO A COR2. It is obscured in C3. Source is a relatively minor eruption from AR 3234 starting around 2023-02-28T17:45Z after the associated M8.6 flare. Post-eruptive brightening can be seen at the time in SDO AIA 304, dimming and UV wave seen in SDO AIA 193, and opening field lines in SDO AIA 171. However, the front of this CME becomes too faint to measure after a couple of frames of C2 and COR2A.

CME Analysis M2M_CATALOG SH true SWPC_CAT 30.0 31.0 346.0 S 28.0 2023-03-01T04:43Z A measurement made with a few initial frames of C2 and COR2A because the front becomes indiscernible in later imagery. The CME is not seen in C3 because it is obscured by the pylon and because of its faintness. The fit in swpc_cat is confirmed by the source location of the associated flare and eruption. 1: Result 1 (2.0 AU)
