Catalog: M2M_CATALOG
Start Time: 2025-12-17T13:45Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
STEREO A: SECCHI/COR2
Activity ID: 2025-12-17T13:45:00-CME-001 (version 1)

Note: This CME is visible to the north in GOES CCOR-1 and to the northwest in STEREO A COR2 imagery. This event is not seen in real-time by SOHO LASCO C2/C3 imagery due to a planned data gap between downlink periods from 2025-12-17T11:48Z to 16:00Z. The source for this event is likely far-sided as there are no source signatures visible on the Earth-facing disk around the time of this event.
