Observer
NameJim M
Experience Level3/5
RemarksIf you draw a line between my location and Norwood Colorado, that is very close to the precise heading at it's lowest observed point. I was driving so I couldn't really stop and stare like I wanted to, but I am pretty sure it kind of went supernova just before it got to the horizon. I don't think it was still burning when it reached my horizon. I did not see any fragmentation, but it was a beautiful fireball!
