Reports Report 408i (Event 408-2012)

Observer
Name Lars
Experience Level 3/5
Remarks Northern central Tennessee, approx. 2 miles south of Kentucky border, driving North on Route 10. Spotted a huge fireball traveling from east to west about 7:15pm CDT (time estimated). Was easily visible on a clear night, huge with a bluish-green color. I’ve seen meteor showers before, but those were generally small streaks across the sky. Difficult to estimate speed or size, but maybe 100 times larger than those small streaks encountered during meteor showers. Never saw anything in the news about it, which is strange considering how large it was. Possibly space junk?
