Kosmopoisk Expedition
As reported by Kosmopoisk, in May 2003 an expedition, performed by Kosmopoisk (leader — V. Chernobrov) reached the 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. Snow and water samples were analyzed and found to contain an abnormal amount of tritium, as well as radioactive isotopes of cobalt and caesium.
Summing up all the information, V.A. Chernobrov suggested that the Vitim event could be caused by a comet nucleus with a diameter about 50–100 meters.

Famous quotes containing the word expedition:
“It is a sort of ranger service. Arnold’s expedition is a daily experience with these settlers. They can prove that they were out at almost any time; and I think that all the first generation of them deserve a pension more than any that went to the Mexican war.”
—Henry David Thoreau (1817–1862)
