Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-12T10:53Z ( STEREO A: SECCHI/COR2 )

All Detecting Spacecrafts:

STEREO A: SECCHI/COR2

Activity ID: 2025-06-12T10:53:00-CME-001 (version 1)

Note Keyword:

Faint: Faint event; may affect type assignment

Source Signature Keyword:

FIL: Filament eruption

Morphology Keyword:

O: Other

Note: CME observed to the west in only STEREO A COR2 imagery. The CME may be too faint/directed away from the occulting disk to observe in GOES CCOR-1, and a large data gap in SOHO LASCO from 2025-06-12T02:45Z-T21:35Z is preventing real-time observation. The source appears to be far-sided, evidenced by lack of on-disk visibility and a single frame of filament ejecta on the west limb viewed from STEREO A EUVI 304 at 2025-06-12T10:15Z which may be the source.
