Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-13T04:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2025-03-13T04:12:00-CME-001 (version 1)
Source Location: S12E90
Active Region Number: 14028
Note Keyword:
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME seen to the ESE in SOHO LASCO C2 and STEREO COR2A for a few frames before it fades, never reaching LASCO C3 imagery. First seen more clearly in SOHO LASCO C2 running difference imagery at 2025-03-13T03:48Z. The source for this CME is likely field line movement in SDO AIA 171 on or just inside the SE limb starting around 2025-03-13T02:53Z, from the northern side of AR 14028.

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
