Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-27T17:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-27T17:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the E in SOHO LASCO C2 starting at 2025-04-27T17:00Z. CME is also visible to the E in SOHO LASCO C3 but is not visible in STEREO A COR2. The CME is visible in running difference imagery one frame earlier than in white light imagery. The source of this CME is most likely a small filament eruption from on/near the E limb starting around 2025-04-27T16:14Z as seen in SDO AIA 304.

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
