Note: This CME is visible to the south/southeast in SOHO LASCO C2 and to the south/southwest in STEREO A COR2 imagery. Not clearly visible in GOES CCOR-1. The source may be related to a small eruption near Active Region 14123 (S42E02) starting around 2025-06-28T17:30Z as seen in SDO AIA 131, 171, 193, 304 imagery. This eruption exhibits deflection to the southwest, possibly related to the coronal hole which is east of Active Region 14123.
