Note: This CME is visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1, and to the southwest in STEREO A COR2 imagery. The source is an eruption visible from beyond the western limb likely from former Active Region 14485 (~S10W110) starting around 2026-07-15T02:30Z as seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 195/304 imagery. An opening of field lines is visible over the southwest limb around this time in SDO AIA 171/193 and GOES SUVI 171/195/284 imagery. Additionally, dimming is observed from the eruption site starting around 2026-07-15T02:55Z seen in STEREO A EUVI 195 imagery.
