Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-08T22:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-06-08T22:24:00-CME-001 (version 1)

Note: CME first seen to the E in SOHO LASCO C2 starting around 2025-06-08T22:24Z. CME also seen to the E in SOHO LASCO C3 and GOES CCOR-1. CME is not seen in STEREO A COR2. The start time is somewhat ambiguous as the CME does not become clearly defined until it reaches the edge of the FOV of SOHO LASCO C2. CME is much more easily distinguished in running difference imagery. There is not a good source candidate on the Earth-facing disk, so the source of this CME could be far-sided.
