Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-19T01:25Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2023-12-19T01:25:00-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:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
U: Unknown
Note: Extremely faint CME seen to the SW in SOHO LASCO C2 and STEREO A COR2. Leading edge is diffuse and therefore carries uncertainty. Source is a small prominence eruption seen on or just beyond the SW limb, centered at a latitude of S30. Liftoff is seen starting at about [enter time later, iSWA maintenance] in SDO AIA 304 and in GOES SUVI 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
