A white/red flashing circular object flying on a highly irregular trajectory.About 10:30pm EST I saw a white/red light flashing flying in a very irregular pattern. It fly straight, veer from side to side, stop completely, and then resume flying (as described). It didn't appear to have any problems with acceleration. After stopping dead in its tracks, it would resume it's previous speed, without the need to accelerate and gradually maintain momentum. I followed it's trajectory (north east) until I lost sight of it.About 10 minutes later, I searched the sky in the direction I had last seen it. I saw a white/red flashing object, that appeared to be circling one area small area of the sky. Again, it would stop suddenly, and continue circling without needing to gradually accelerate. Unclear if it is the same object from earlier.
