Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-24T21:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-01-24T21:24:00-CME-001 (version 1)
Source Location: S05W70
Active Region Number: 13961
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint CME seen to the NW in SOHO LASCO C2 only - this CME fades after a few frames and is overlapped by further activity from AR 13961. Furthermore, it is only visible in running difference imagery, as a bright streamer hides this front in white light imagery. However it has a clear source, as the M2.7 class flare from AR 13961 best seen in SDO AIA 131, with field line movement in SDO AIA 171/193/211 and filament ejecta in SDO AIA 304.

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
