Start Time: 2025-06-08T17:12Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

Activity ID: 2025-06-08T17:12:00-CME-001 (version 2)

Source Signature Keyword:

Morphology Keyword:

Note: This CME is faint but visible to the west/southwest in SOHO LASCO C2 imagery for a few frames before becoming too diffuse to observe. Not clearly visible in STEREO A COR2 or GOES CCOR 1. The source is likely far-sided as there are no source signatures on the Earth-facing disk around the time of this event.
