I am not sure if this was technically a fireball or not; I was still looking out the window from my basement and a large super bright light appeared and streaked across a small part of the sky very quickly. My basement window faces north directly and it never left the field of vision of my window. It was much brighter than a shooting star or Venus...and was only there for a second or too and was bright white. I am not sure what else it could have been unless there was some sort of electrical explosion on a powerline or something.
