Note: This CME is visible to the East in SOHO LASCO C2, C3, GOES CCOR-1, and STEREO A COR2 imagery. The source may be a filament eruption starting around 2025-06-11T18:27Z between S00E40 and S20E60 as seen in SDO/AIA 304 with brightening and dimming seen in SDO/AIA 193. There is a large coronal hole to the south of this eruption which may have contributed to deflection of the CME.
