Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-02-28T09:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
Activity ID: 2023-02-28T09:53:00-CME-001 (version 4)
Source Location: N20W30
Active Region Number: 13234
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Very faint CME in the NW in both coronagraphs first seen after the end of the nighttime data gap in STEREO A COR2. The start is currently covered by the data gap in SOHO LASCO but it is also faintly seen in C3 after this gap. One possible (front-sided) source could be a relatively minor eruption seen after 2023-02-28T06:19Z in AIA 304, 171, 193. In SDO AIA 304 there is a bright flare, then dark material (possibly ejecta). Brightening then dimming of area seen in GOES SUVI 284. It could be associated with a C2.5 class flare from AR 3234 at the time (N20W30). However, this faint event could also be back sided (no coronal signatures found for this).
