 DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-12T19:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-12-12T19:12:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
LS: Loop and Shock Candidate
Note: Bright CME seen to the SE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The source appears to be just beyond the E/SE limb in SDO/AIA 193, 171, 304, and GOES SUVI 284 with a rising loop and associated moving/opening field lines seen along the E/SE limb starting around 2023-12-12T18:45Z. A filament along the SE was also seen moving due to this eruption, but doesn't appear to erupt. Following the eruption, post-eruptive arcades are visible starting around 2023-12-12T21:00Z best seen in SDO/AIA 193 and 171.
