Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-07T12:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-07T12:00:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright loop front CME with outflowing material following it to the NE in SOHO LASCO C2, C3, STEREO A COR2, and GOES CCOR-1. The source is a filament eruption in the NE starting around 2025-05-07T11:00Z in SDO/AIA 304, 171, 131, and 193. The filament appears to stretch over the NE limb, possibly by 20 degrees based on a rough STEREO A EUVI 304 calculation. There is limited imagery available in STEREO A COR2 due to a data gap for most of this event.
