they look like stars of varying brightness and size (maybe distance related)

I flashed UFO and it reversed course to overhead and for a 2 hour period did not move other than to stay in formation with its local star constellation as the night sky slowly moves from east to west.

first UFO seen after 10 minutes, I flashed it and it reversed course moving in line with with a star formation. There it remained throughout the entire episode. From this point onwards I must have seen at least 15 more ufo's. I flashed all of them with all but say 5 freezing, reversing course. the others continued at a constant speed. All came from south to north. I have much more to add but there is a time limit on your website for putting this info in.
