Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-15T16:24Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

GOES: CCOR-1

Activity ID: 2025-10-15T16:24:00-CME-001 (version 1)
Source Location: N22W53
Active Region Number: 14246

Note Keyword:

DFL: Likely deflection of the event within the FOV

OVR: Event partially overlaps with another CME

Source Signature Keyword:

FLR: Flare

OFL: Moving/Opening field lines

DIM: Dimming

Morphology Keyword:

FS: Flux Rope and Shock Candidate

Note: CME visible to the NNW in SOHO LASCO C2/C3 and GOES CCOR-1 as well as the NNE in STEREO A COR2. Overlaps in the field of view with CME: 2025-10-15T15:36Z. The source of this event is an M1.1 flare from Active Region 14246 (N22W53) which peaked at 2025-10-15T14:10Z. This flare can be seen in GOES SUVI 131 along with dimming and field line opening seen in GOES SUVI and STEREO A EUVI 195. This dimming and field line opening appears to be directed northward, suggesting northern deflection of the CME.
