Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-04T07:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-04T07:12:00-CME-001 (version 3)
Note Keyword:
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Very narrow CME seen to the W in SOHO LASCO C2/C3 and STEREO A COR2, which becomes diffuse halfway through the STEREO A COR2 field of view. The precise source is unclear, but several small instances of field line movement on can be seen just beyond the SW limb occurring between 2025-04-04T05:00Z-07:00Z in STEREO A EUVI 195 from a bright cluster of formerly numbered ARs, including ARs 4047, 4040, and 4042, which together span from about latitude S00 to S20 and longitude W90 to W110.

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
