RE: (meteorobs) Fwd: DoD Fireball Detection



And just so no one gets too excited, note that the IMPACt referred to is 
with the atmosphere, not the ground! Last trached height 23 km, which gives 
it at least 3 or 4 minutes for the outer 1 millimeter of the surface to 
cool.

Fireball Detection

On 5 December 1999, infrared sensors aboard DOD satellites detected
the impact of a meteoroid at 10:17:58 UTC about midway between
Montgomery and Birmingham, Alabama.  The object was first detected at
about 33.1 North Latitude, 85.9 West Longitude, at an altitude of
approximately 74 km. It was traveling on a path from just east of
north to just west of south, at an angle of about 55 from the
horizontal.  It was last tracked at an altitude of approximately 23km
at 33.0 North Latitude, 86.1 West Longitude.
