On June 30, 1908, the Tunguska catastrophe occurred. On the same day, the meteorite Kagarlyk fell near Kiev. However, no connection between these events has been confirmed. See more
The Kagarlyk meteorite is a L6 chondrite that fell on 30 June 1908, a few hours after the Tunguska event, near Kagarlyk settlement, about 200 kilometres southeast of Kiev. A mass is 1.886 kg was recovered. The exposure age of Kagarlyk was determined to be 16.2 million years, which is typical of many L-chondrites. Apart from the temporal proximity of the fall of the Tunguska event Kagarlyk it is otherwise a rather typical L-chondrite. It is often argued that a fortuitous coincidence in time with the Tunguska event is unlikely and therefore a connection must exist.
Traynerl has outlined some recent investigations of the Tunguska event of 1908. Recently several groups have tried to ascertain the physical nature of the impactor (cometary or asteroidal composition?) on the basis of the model of its atmospheric detonation. The fact that a meteorite fell near Kiev within five hours of the explosion, and which might therefore be plausibly suggested as a fragment released prior to meeting the Earth, seems to have been overlooked by most researchers, but has now been pointed out by Hasegawa.
