6.85 grams. 18 x 16 x 12 mm. Ureilite-an
TKW 3.95 kg.
Pre-Earth-encounter size estimated to be 4.1 meters in diameter and 80,000 kilograms.
Observed approach: 6 October 2008
Observed fall: 7 October 2008
First found: 6 December 2008, Nahr an Nil, Nubian Desert, Sudan.
Many stones from this fall have been classified, with a wide variety of results - Ureilite, polymict, anomalous; bencubbin; EH 4/5; and EL 3.
From the MetBul:
On October 6, 2008, a small asteroid called 2008 TC3 was discovered by the automated Catalina Sky Survey 1.5 m telescope at Mount Lemmon, Tucson, Arizona, and found to be on a collision course with Earth. Numerous astronomical observatories followed the object until it entered the Earth’s umbra at Oct. 7.076 UTC the next day. The astrometric position of 295 observations of 2008 TC3 over the period Oct. 6.278 to Oct. 7.063 was used to calculate the approach trajectory over the impact location in northern Sudan. The object exploded at a high ~37 km altitude over the Nubian Desert, and as a result the meteorites are spread over a large area. A search was organized by the University of Khartoum on Dec. 2–9, led by P. Jenniskens (SETI Institute) and M. H. Shaddad (Khartoum).
