Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-20T01:08Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-11-20T01:08:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: CME first seen to the SW in STEREO A COR2 beginning at 2025-11-20T-1:08Z, as well as by GOES CCOR-1 and SOHO LASCO C2/C3 in later frames. The source of this CME is a large filament eruption seen along the Southern limb, likely tracing to the far side seen in GOES SUVI 304 beginning at approx. 2025-11-20T00:32Z.
