A bright fireball is seen shooting over Vanavara on the Stony Tunguska River in central Siberia, Russia, exploding 5-10km above the forest, knocking trees flat over 2150km2 area, burning an area 1000km2, sucking ash 20km into the atmosphere, incinerating many herds of reindeer and killing a few people. The explosion is heard 1000km away. The object, likely a comet or asteroid fragment, is estimated to have been 1-5 tons, 156m diameter.
