Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-04T18:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-06-04T18:48:00-CME-001 (version 1)
Source Location: N12E60
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint, diffuse CME visible to the NE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. Not clearly seen in GOES CCOR-1. The source may be associated with a quick eruption and field line movement from an area near N12E60 as seen in SDO/AIA 193 starting around 2025-06-04T17:15Z.

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 |
