My wife noticed this out the window, so I tried to figure out what it was, downloaded skyview, which pinned this between Enif and Z Cyg (first two screenshots). Finally another pic showing how bright it was. ISS actually passed through in the middle of figuring this out, which was a cool surprise, but as the ISS left, this remained. Seems to be moving very slowly, but in a different direction than skyview is indicating other stars are moving?
This was in the western sky to me, from just south of Winston Salem, NC.
