6.59 grams.   Ureilite-an

TKW 3.95 kg. Observed fall in Nahr an Nil, Nubian Desert, Sudan.

From the MetBul:
Observed fall 7 October 2008, 05:46 h local time (UT+3)

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).


There have been many stones from this fall classified, with a wide variety of results - Ureilite, polymict, anomalous; bencubbin; EH 4/5; and EL 3.

A very nice sample and very appropriate for display at the Smithsonian. I have spent hours and hours in not only the hooker hall of gems and minerals but obviously in a meteorites section.

Thank you, glad you both like it. Larry, I don't know if the site is open to the public, but it will be part of a display in the Arizona Congressional Office, with an explanation of how it was discovered by Richard Kowalski and the Catalina Observatory. Do take a picture if you get to see it, I would love to see it.
