This was extremely brief and I only saw it outside my window; however, it was extremely bright. The arc was very small. It may have been visible prior to it coming into the frame of my window. It exploded and disappeared almost as soon as I saw it. The entire viewing was far less than a second.

Remarks
I saw a bright green light come into view outside my window, quickly change to red, then became white and expanded to nothing. It did not seem to go very far down into the atmosphere before it exploded.
