For over a year, myself and other employees have watched 3 same lights over part of our town from 20:00-0700.. Can watch them slowly come from the northeast and hover above our workplace the entire nite.. One bright light seems to be the main one along with 2 smaller lights sitting in a triangle shape.. all have red and blue flashing lights along with bright white light and seem to spin..last week a sphere shaped loud one came from nowhere by these lights and darted all over the place and then disappeared
