Circular light appeared instantly in the South, going East for 6 minutesCircular light appeared instantly in the South. It continued toward the East for about 6 minutes. It was extremely slow. Magnitude of -1 or -2 at first, then down to +1 or +2. I was using Venus as a gauge for the magnitude as it was in the night sky at the time.These objects are seen at least twice a month by myself and co-workers, usually just after dusk or before dawn.
