Chickamauga, GA Fireball Meteor 2:27 AM CDT (2013 August 28 07:2721 UTC)

Last night at approximately 2:27 AM CDT (2013 August 28 07:2721 UTC), all 6 NASA allsky cameras in the SouthEast picked up a very bright fireball (peak magnitude ~ -11, 2 magnitudes brighter than the Last Quarter Moon) that MAY have produced meteorites. The cameras were completely saturated, necessitating a manual solution. This may very well be the brightest event our network has observed in 5 years of operation.
Using two stations, we have derived the following crude parameters:

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)
Speed: 23.7 km/s
Peak brightness: -10.9
Mass: ~45 kg (roughly 0.3 to 0.4 meters in diameter)
Radiant: RA - 336 +/- 2 deg, Dec +9.8 +/- 4 deg

About an hour ago; 7:30 p.m. EST, 9-28-2013, Chickamauga, GA we viewed an apparent large meteor/fireball sighting; traveling west to east; Sparks were coming off and then burned out. Were there any other sightings of this? Miller/Glenfield
