I did not personally witnessed this. This I s from a surveillance camera on the north side of my house. It could have been a helicopter with a searchlight, but it definitely looks like the light is coming from directly overhead and is extremely bright. Duration and the movers seem consistent with other videos I have seen of fireballs. I’m sorry that I didn’t yet a better shot at it.
