Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-02-20T21:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-02-20T21:48:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright CME seen traveling along the streamer in the NE of SOHO LASCO C2/C3 and STEREO A COR2. Potential source is an eruption on or just beyond the NE limb in SDO AIA and STEREO A EUVI imagery. A filament can be seen lifting off of the NE limb in SDO AIA 304 and STEREO A EUVI 304 starting around 21:00Z. Opening field lines can also be seen in SDO AIA 171/193. Data gap in STEREO A COR2 from 2023-02-20T23:53Z to 2023-02-21T04:23Z.

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
