Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-20T14:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-02-20T14:24:00-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:
LS: Loop and Shock Candidate
Note: CME to the NW in SOHO LASCO, fully covered by a large data gap in STEREO A COR2 from 2024-02-20T13:53Z to 2024-02-21T03:09Z. The source is a narrow opening field lines and rising loop just beyond the NE limb at an apparent latitude of N17, seen in SDO AIA 171/193 starting at 2024-02-20T14:15Z. Ejecta seen is also in SDO AIA 304 starting as early as 2024-02-20T14:06Z.

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
