Sikhote-Alin is an iron meteorite that fell on February, 13, 1947 on the Sikhote-Alin Mountains in eastern Siberia. Though large iron meteorite falls had been witnessed previously and fragments recovered, never before in recorded history had a fall of this magnitude been observed. An estimated 70 tonnes of material survived the fiery passage through the atmosphere and reached the Earth. The strewn field for this meteorite covered an elliptical area of about 1.3 km2 (0.50 sq mi). Some of the fragments made impact craters, the largest of which was about 26 m (85 ft) across and 6 m (20 ft) deep. Fragments of the meteorite were also driven into the surrounding trees. The Soviet Union issued a stamp for the 10th anniversary of the Sikhote-Alin meteorite shower and this reproduces a painting by P. J. Medvedev, a Soviet artist who witnessed the fall: he was sitting in his window starting a sketch when the fireball appeared, so he immediately began drawing what he saw.
