The station is in remote Tunka valley, in the Republic of Buryatia, an ideal vantage point for observing incoming meteors because of the absence of artificial lighting. Created by the astronomical observatory of the Irkutsk State University (ISU), it operates from two unmanned modules some 58 kilometres apart. This allows researchers to observe the same meteor from two different locations, and to measure its size, light energy, direction, weight of meteoric particles and other parameters, more precisely.

Picture: The Siberian Times Kirill Ivanov, researcher at ISU's observatory, explained that the cameras are pointed in such a way that the centres of their field of view match at a height of about 100 km. 'They ensure maximum overlap of the field of view, two thirds, at a height of about 80-120 km. The data is stored in industrial computers.' On a clear night, the equipment has registered up to 40 meteorites. On 22 October, two weeks after the facility opened it recorded recorded a bright fireball, flying from west to east, over the mountains of Mongolia and Buryatia. Having originated in the Asteroid Belt, the meteorite's journey ended as it sank into the waters of Lake Baikal, about 1 km from the shore, and 17 km from the village of Bolshoye Goloustnoye. 'Most likely that meteorite fell under the 'bad' influence of Jupiter, and away from its 'true path',' said Ivanov. Its initial mass was around one kilogram, its size - about 10 centimetres. This meteorite - shown in the video here - was also spotted by locals. A key research aim is to expand our knowledge of the meteors, their characteristics and paths. In November researchers plan to observe the prolific Leonid meteor shower. This occurs when the Earth crosses the orbital path of Comet Tempel-Tuttle. The comet litters its orbit with fragments of bits of debris which enter the Earth's atmosphere and vaporise. Received on Wed 04 Nov 2015 04:35:46 PM PST |
