Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-23T08:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2025-04-23T08:38:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME visible to the SW in STEREO A COR2 imagery. No SOHO imagery available currently due to a data gap. The source appears to be beyond the SW limb starting around 2025-04-23T07:53Z in GOES SUVI 284 and SDO/AIA 171 as moving/opening field lines. The source is not clear in STEREO A EUV imagery.

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
