Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-05-29T02:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-05-29T02:12:00-CME-001 (version 1)
Active Region Number: 13318
Note Keyword:
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
SB: Streamer Blowout following CME
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: Seen to the NW in SOHO LASCO C2/C3 and STEREO A COR2. This is the first of multiple fronts seen in coronagraph imagery, which were caused by several consecutive filament eruptions/a filament erupting in multiple stages on the Earth-facing disk. At about 2023-05-29T01:15Z as seen in SDO AIA 304, the large filament is seen breaking near AR13318 (N25W20 at the time) (no flare had occurred, however) and the first segment begins to lift off.

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
