Fragmentation
Observation	Yes
Remarks	It was breaking up as I first glimpsed it; appeared to have been moving very fast across the sky then the light or exploding part almost end halted in the same spot on the sky before breaking up into maybe 3 pieces; these fragments appeared to almost 'rain down', that is, they made an umbrella shape as they faded out and appeared to fall toward the ground. This is unlike just before the explosion (which I didn't really see, but got the impression the light was zooming along a strait line prior to fragmentation. The line would have run from ESE toward north or NE, the line crossing the N horizon with a steep incident angle, about 10 or 20 degrees. It's difficult to explain without using my hands or an illustration.
