Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-19T19:24Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

GOES: CCOR-1

Activity ID: 2025-10-19T19:24:00-CME-001 (version 1)

Note Keyword:

Faint: Faint event; may affect type assignment

FF: Event fails/disappears before exiting COR2

GAP: Data gap

OVR: Event partially overlaps with another CME

Source Signature Keyword:

FIL: Filament eruption

Morphology Keyword:

L: Loop

Note: Narrow faint CME seen to the NNW in SOHO LASCO and GOES CCOR-1, mostly in running difference imager. Overlaps with/is partially obscured by the outflows following the NW streamer blowout CMEs: 2025-10-19T06:36Z and 2025-10-19T10:36Z Completely covered by a large data gap in STEREO A. Source: possibly the prominence seen in the NW in SUVI 304 at 2025-10-19T19:25Z and seemingly deflecting northwards.
