Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-08-03T04:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-08-03T04:38:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
JS: Jet and Shock Candidate
Note: Narrow faint CME seen to the SW in STEREO A COR2 and SOHO LASCO coronagraphs. Its source is faint and narrow rising loop / opening of field lines seen on or, more likely, beyond the SW limb starting around 2025-08-03T04:05Z in GOES SUVI 304. It is seen also in SDO AIA 193 starting at 2025-08-03T03:57Z.

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.
