Note: This CME is visible to the northeast in SOHO LASCO C2 and STEREO A COR2 imagery. The source is likely an eruption from Active Region 14479 (N16W15) starting around 2026-06-30T13:30Z which exhibits northern deflection as seen in SDO AIA 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery. Dimming is observed northeast of the eruption site in SDO AIA 193 imagery.
