Note: Narrow CME seen to the south in SOHO LASCO C2/C3 and GOES CCOR-1. Seen to the southeast in STEREO A COR2. Source is uncertain. Source may possibly be some very subtle opening field lines seen from Active Region 14121 (S12E01) around 2025-06-25T20:19Z. Some very small post-eruptive arcades are seen at AR 14121 at 2025-06-25T19:27Z seen in SDO AIA 193, with some very gradual field line reconfiguration in a small area just to the southwest of AR 14121 afterwards, but this is a very minor signature.
