Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-11-05T22:00Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

GOES: CCOR-1

Activity ID: 2025-11-05T22:00:00-CME-001 (version 2)
Source Location: N30E41
Active Region Number: 14274

Note Keyword:

OVR: Event partially overlaps with another CME

Source Signature Keyword:

Morphology Keyword:

Note: This CME is visible to the north/northeast in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery and partially overlaps with the halo CME: 2025-11-05T22:23Z. The source of this event may be related to the impulsive M8.6 flare from Active Region 14274 starting around 2025-11-05T22:00Z, the same source as 2025-11-05T22:23Z, as there appear to be multiple ejections of material associated with this flare which are deflected northward.
