Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-04T10:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-04T10:48:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Fast, diffuse CME to the SW in SOHO LASCO C2, C3, STEREO A COR2, and GOES CCOR-1. The source appears to be a filament eruption from beyond the SW limb of STEREO A EUVI 304 starting around 2025-05-04T10:15Z. Associated moving/opening field lines are visible in SDO/AIA 171 along the southern limb.

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
