Note: Narrow CME seen to the N in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. Source is uncertain, but opening field lines may possibly be seen on or beyond the North limb in STEREO A EUVI when toggling between frames with timestamp 2025-06-30T18:55Z and 19:05Z in STEREO A EUVI 193. These opening field lines may also seen in STEREO A EUVI 304 between frames 2025-06-30T17:45Z and 19:15Z.
