The 2002 Vitim event or Bodaybo event is believed to be an impact by a bolide 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.〔 Attempts were made to define the magnitude of the explosion. U.S. military analysts calculated it was around .〔 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.〔 Russian physicist Andrey Olkhovatov estimates it at 4–5 kilotons. 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 MChS (Emergency Rescue) team tried to find an object 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 a remote Siberian taiga. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2002 Vitim event」の詳細全文を読む スポンサード リンク
