Reports Report 278b (Event 278-2015)

Observer
Name David K
Experience Level 3/5
Remarks I am the county emergency management coordinator and was returning from an out of town trip with my deputy coordinator. We were driving up the street when this occurred in the night sky directly ahead of us. He spotted it first, said "look" and I leaned forward because the roof above the front windshield was shielding my view and I then saw what I just reported. Wish we'd have had a camera!!

Terminal flash
Observation Yes
Remarks At the end of the silvery trail (which was three parts...an inner core trail flanked by two outer trails all from the same core point, it just sort of winked out and then we briefly saw three orange chunks starting to scatter outwards from that terminal point.
Fragmentation
Observation Yes
Remarks No flash, just the bright silver trail went out and three orange chunks began scattering outwards and forwards of that point. they were only visible for a very brief period...time it takes to blink a human eye. But, they appeared to have more mass than the width of the silvery sparkly trail we had observed up to that point.
