Watching sky in back yard with my wife. 3 not so bright rings appeared in the south at an unknown altitude moving very fast. we could not tell if they were solid or hollow. like hula hoops but fuzzy. red in color, no noise at all. in a reverse v pattern at first then the middle hoop moved to the front of the v i watch the sky all the time and have never seen the likes of these. total time from south to out of sight north 3 to 6 seconds. weather was clear with very good visibility.
