All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2

Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
L: Loop
Note: Loop CME seen to the SW in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. One candidate source is the possible partial eruption of a long filament seen in the SW quadrant of the STEREO-A-facing disk. The long filament is seen starting to move at about 2025-06-30T13:45Z with possible partial liftoff of a portion centered at about S20W130 (heliographic coordinates) seen between the STEREO A EUVI 304 frames timestamped 2025-06-30T15:15-15:45Z.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.
