50 kg meteor explodes and illuminates sky over southeastern US

A meteor with estimated mass of over 50 kg exploded over Tennessee, US, around 07:27 UTC on August 28, 2013 (02:27 local time). Head of NASA's Meteoroid Environment Office, Bill Cook, said the fireball reached a peak magnitude of -13. It was brighter than a full moon, and casted shadows on the ground. This indicated that the meteor had a mass of over 50 kg (110 lbs) and was about 40 cm (16 inches) in diameter.

All 6 NASA's all sky cameras in the southeast picked up a very bright fireball that may have produced meteorites. The cameras were completely saturated, necessitating a manual solution.

It hit the top of Earth's atmosphere traveling 23.7 km/s (53,000 mph).

"As far as I know, this is the brightest event our network has observed in 5 years of operation," he continues. "There are reports of sonic booms reaching the ground, and data from 4 doppler radars indicate that some meteorites may have fallen along the fireball's ground track."

Using data from multiple cameras, Cooke has calculated a preliminary orbit for the meteoroid. The shape and dimensions of the orbit are similar those of a Jupiter-family comet.

If meteorites are recovered from the Tennessee countryside, their chemical composition will tell researchers more about the origin of the fireball.

Start location: 84.943 W, 34.969 N at an altitude of 97.4 km
Last location: 84.578 W, 35.206 N at an altitude of 37.9 km (this is not the lowest point; other stations show it continuing)

I’ve watched this video several times … the apparent meteor seem to have originated from over the earth, not from deep space … which gives opportunity to repeat the true possibility of how there are 4 upper dimensional levels of open skies tucked away in the 4 levels of Earth’s ionosphere, each referred to as a heaven .. the very foundations of these tucked away open skylines are sustained by the earth’s core gravitational field .. when there are changes in the earth there are changes in the heavens .. and these heavens are being shaken … and unorthodox advance technology are falling .. 2 Corinthians 12:2 I knew a man in Christ above fourteen years ago, ° (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven.

Wow, just enough science in that comment to make people think you know what you're talking about. Too bad its all BS lol. Do try to keep your religious filth out of our science. Thanks.
