(meteorobs) Lower Midwestern USA Fireball June 5, 2012

[Esko Lyytinen]

Hi Robert and all,

I derived rough directions from James Beauchamp's all-sky camera and 
Kevin Palivec's "direct view" camera(s).
Both cameras were earlier calibrated but had their directions changed 
since. And now no stars were visible. I used distant (street)lights to 
derive the new camera directions roughly.

I also get the expected landing site WNW of Clinton. ( No actual dark 
flight simulation done.)
But the velocity seems to be around 30 km/s ( 32 km/s but with quite 
wide error margin). So I expect this to have mostly ablated away. 
Something very small may have came down, but not enough for a search, I 
think.

I get it arriving from az-direction 116 with the slope of 17 degrees. 
And I have the end height in James's camera at 43 km, but this was not 
yet the real end of the luminous flight.
The apparent radiant on the sky was 264, -10. So this seems to have been 
of the antihelion type.
