I really don't know what it was. It definitely wasn't a firework and it was as bright as a the full moon was. I don't have much astronomy experience and really hope someone can come back confirming or denying really.

Afterwards there was a low rumble, softer than thunder but still definitely there.
The bright light happened at the same time as a crackle and that's when I turned and saw it.
Whatever I saw broke apart 2-3 seconds after I saw it first. There was a bright light at first which dimmed some.
