Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-25T15:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-02-25T15:48:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Faint CME to the NW in SOHO LASCO C2/C3 only, missed in STEREO COR2A due to a data gap. The CME travels into the pylon in C3 hindering visibility in white light and running difference imagery. The source is observed as a field line loop breaking over the NW limb around 2025-02-25T14:18Z in SDO AIA 171/193, potentially from old AR 4001 which rotated over the NW limb on 2025-02-24.

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
