Bluish circle moved quickly across the sky and dsappearedFacing east, I noticed a blue circle with white around the outside of it and a blue/white tail behind it. It was very low in the sky and kind of looked like the ball out of a roman candle. However, it moved from north to south across the eastern sky fairly low and there were no other ones before or after it appeared. There was no sound associated with it and it quickly disappeared with no visible smoke or anything left behind leading me to think it was not any type of firework. It was also too low in the sky to be shooting star.
