Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-21T22:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-09-21T22:36:00-CME-001 (version 2)
Source Location: S35W97
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: Bright light-bulb shaped CME to the SW in SOHO LASCO, with the start covered by the data gap in STEREO A COR2 (the gap starts right before the CME start). The source is a large prominence from behind the SW limb in GOES SUVI 304 and in the SW quadrant, not far from the SW limb in STEREO A EUV 304 and 195. The filament is centered around (S35W50) as seen from STEREO A, so around (S35W97) as we would see from Earth.
