I had just finished walking my dog and it was at 7:50 pm or a minute or two after. i was looking to see if bats were flying around in the last light although now it was pretty dark. to the northwest i saw two stars close to each other and i was wondering what constellation that was since it was unfamiliar. they were vertical, maybe a little like orions belt. then the one on the right just vanished. it didn't move, it just disappeared. they were almost like venus in brightness, two of the three brightest stars( one wasn't a star, that was the ufo.) in the sky then. as i was looking to see if it might reappear, i saw a jet flying overhead east to west. there weren't any clouds, its a clear night.
