2002 Vitim event

Vitim bolide impact site

The 2002 Vitim event or Bodaybo event is believed to be an impact by a bolide (fireball) in the Vitim River basin. It occurred near the town of Bodaybo in the Mamsko-Chuisky district of Irkutsk Oblast, Siberia, Russia on September 25, 2002 at approximately 22:00 (local time, UTC/GMT +9 hours: ISO 8601 format 2002-09-25T13:00Z). The event was detected by a US military missile-defense satellite.[1]

## Analysis

Attempts were made to define the magnitude of the explosion. U.S. military analysts calculated it was around 0.86 terajoules (0.21 kilotonnes of TNT).[1] Peter Brown estimates the total yield of both Bodiabo and Tagish Lake at about 2 kilotons—a factor of roughly 10,000 less than the Tunguska event.[1] Russian physicist Andrey Olkhovatov estimates it at 4–5 kilotons.[citation needed]

Information about the event appeared in the mass media and among scientists after only a week. A small expedition, sent by the Institute of Sun–Earth Physics (Irkutsk), tried to find a meteorite within about 10 km from Bodaybo town (people told them– "it has fallen beyond the nearest mountain").

## Expeditions

* 1st — Russian EMERCOM team attempted to find fragments of the meteorite near Bodaybo.
* 2nd — October, 2002 expedition of Irkutsk State University (leader S. Yazev).

Official expeditions in 2002–2003 never reached the impact site, situated in remote Siberian taiga.

## Kosmopoisk expedition

As reported by the ufology organization Kosmopoisk, in May 2003 an expedition, performed by Kosmopoisk (leader -- Vadim Chernobrov) reached a presumed impact point (about 50 km from Vitimsky settle point). The situation there looked similar to that of the Podkamennaya Tunguska River after the Tunguska event in 1908.[citation needed][dubious - discuss] Snow and water samples were analyzed and found to contain an abnormal amount of tritium, as well as radioactive isotopes of cobalt and caesium.[citation needed] Chernobrov suggested that the Vitim event could be caused by a low density comet nucleus with a diameter of about 30–100 meters.[citation needed]
