Ever see this one?
DOD Satellite Observations
"On 9 December 1997, sensors aboard DOD satellites detected the impact of a meteoroid at 08:15:55 UTC roughly midway between Nuuk and Qaqortoq, Greenland. The object broke into at least 4 pieces. One piece detonated at an altitude of about 46 km at 62.9 degrees North Latitude, 50.9 degrees West Longitude. The remaining 3 pieces detonated in close proximity to one another at altitudes between 28 km, at 62.9 degrees North Latitude, 50.1 degrees West Longitude and 25 km at 62.9 degrees North Latitude, 50.0 degrees West Longitude."

****************************************************************************
On 9 December 1997 at approximately 08:15:55.2 UT, sensors aboard a
U.S. Department of Defense satellite recorded the bright flash of
an apparent meteoroid disintegrating in the atmosphere over
Greenland. The peak radiated intensity recorded on this event
was 9.5E10 watts/sr (using a 6000K blackbody model for the
radiation). Correspondingly, the total radiated energy of the
event was 2.7E11 Joules.

Fortunately, Greenland can be seen every three hours in the GOES-8 thermal infrared channel ("I04", or Imager channel 4 at 11 microns) with lower resolution:

Yeah, that's very cool (you posted it in the other thread, too). Subsequent expeditions to the area attempted to find an impacting object, but only discovered micrometeorite fragments in meltwater.

That's pretty neat. I had not see the animation before. Thanks.
