Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-08T15:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-05-08T15:12:00-CME-001 (version 1)
Source Location: S20W80
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME seen to the SW in SOHO LASCO C2/C3 and STEREO COR2A. The source may be field line movement tracing to around S20W80, observed in SDO AIA 171/193 starting at 2025-05-08T14:40Z. This is the fainter of two concurrent fronts, followed by a brighter CME: 2025-05-08T16:24Z in the same direction which may share this source.

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
