Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-15T04:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-15T04:48:00-CME-001 (version 1)
Source Location: N25W45
Active Region Number: 14246
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: CME first seen to the NW by SOHO LASCO C2 beginning at 2025-10-15T04:48Z, as well as by SOHO LASCO C3, STEREO A COR2, AND GOES CCOR-1 in later frames. The source of this event is an M4.8 class flare from Active Region 14246 (N25W45) which peaked at 2025-10-15T04:15Z. This flare can be seen clearly in GOES SUVI 131, along with dimming and field line opening seen in GOES SUVI and STEREO A EUVI 185. The dimming appears to propagate Northward, suggesting a Northern deflection of this CME.
