When I saw it, I was looking in the direction of the setting sun. At the time I had no idea what it was but the first thing that came to mind was "that looked exactly like a fireball falling to earth". There had to be more people who saw it. So I am not sure what it was but if you took a picture of it and put it in the dictionary for the definition of a fireball. It would have been perfect. It was big. It was fast.
