Note: CME first seen to the WNW in SOHO LASCO C2 starting at 2026-06-17T17:48Z. It is also seen to the WNW in SOHO LASCO C3, GOES CCOR-1, and STEREO A COR2. This is the first in a series of three CMEs. The source is an eruption from Active Region 14464 (~S14W96) starting around 2026-06-17T17:30Z as seen in SDO AIA 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery.
