While this sighting appeared to traveling east-west in two dimensions, I think it was traveling away from my location, so on a northwesterly heading.

I saw a streak of white then bright blue light which turned orange then exploded in orange fragments, very similar to an aerial firework. No sound. (No, it was not a nearby idiot sending up fireworks.)
