On september 13, 1937 at 14:15h a fireball was observed in Kainsaz, Russia. It left a dust train and broke into fragments during flight in a series of detonations that were heard up to 130 kilometres away. Fifteen pieces of the Kainsaz meteorite were seen to fall near Kainsaz, Tatarstan. The strewn field of 40 by 7 kilometres was oriented SE-NW with the largest stone falling at the NW end. Kainsaz is classified as a CO3.2. This stands for CO group, petrologic type = 3, and subtype = 2. The group is part of the CM-CO clan and a member of the carbonaceous chondrites.
