Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-15T15:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-15T15:36:00-CME-001 (version 1)
Source Location: S05W30
Note Keyword:
HAL: Halo CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
F: Flux Rope
FS: Flux Rope and Shock Candidate
Note: Partial halo CME visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1 and the north in STEREO A COR2. The source of this event is a region of dimming seen centered at approximately S05W30 beginning at approximately 2025-10-15T14:04Z as seen in GOES SUVI and STEREO A EUVI 195. This dimming is also accompanied by wide opening field lines seen in GOES SUVI 195, 284 and STEREO A EUVI 195.
