Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-01-31T00:12Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2026-01-31T00:12:00-CME-001 (version 1)

Note Keyword:

DFL: Likely deflection of the event within the FOV

Faint: Faint event; may affect type assignment

GAP: Data gap

Source Signature Keyword:

FIL: Filament eruption

Morphology Keyword:

O: Other

Note: Diffuse, faint CME observed to the NE in SOHO LASCO C2/C3 and GOES CCOR-1, not in STEREO A COR2 due to a data gap. The source may be filament ejecta just on/beyond the east limb starting around 2026-01-30T23:21Z in SDO AIA 304, deflecting northward.
