Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-07T15:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-10-07T15:12:00-CME-001 (version 1)
Source Location: S45W20
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
J: Jet
Note: Narrow CME seen due south in SOHO LASCO C2 and not seen in STEREO A COR at the time of analysis due to a data gap; the CME may potentially be associated with a minor filament eruption located on the Earth-facing disk near 2025-10-07T14:00Z around S45W20 with southern deflection, though confidence is relatively low with currently available imagery.
