I'm not exactly sure on the time. We were outside shortly after it was completely dark but didn't look at the time immediately afterwards, it probably could have been between 8 and 9 o'clock P.M. but I think closer to 8.

It looked like a small firework that came down vertically out of the sky and then flashed and split into a few smaller fragments that quickly disappeared
