Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-12T16:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-12T16:24:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
U: Unknown
US: Unknown and Shock Candidate
Note: CME visible to the southwest in SOHO LASCO C2/C3 and STEREO A COR2. The source can be seen on the southwest limb in STEREO A EUV 195 at 2025-04-12T16:00Z with rapid opening of field lines, brightening, and post-eruptive arcades. The eruption can also be seen beyond the limb as an ejecta of material in GOES SUVI 304 imagery. A faster, fainter shock appears to travel ahead of the leading edge of the CME.

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
