Start Time: 2025-06-19T00:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-06-19T00:09:00-CME-001 (version 1)

Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Narrow CME visible to the NW in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. The potential source can be seen as opening field lines beyond the west limb in GOES SUVI 284 starting at 2025-06-18T23:34Z. The eruption is not clearly visible in STEREO A EUV imagery.
