Seymchan is a pallasite meteorite found in the dry bed of the river Hekandue in the Magadan district of Russia. The main body of 272.3 kg was found in June 1967 by the geologist F.A. Mednikov, with another 51 kg specimen located nearby in October of the same year by I.H. Markov. The main mass was given to the Academy of Sciences of the USSR. Another 50 kg was found in a later expedition of 2004, which revealed the inclusion of olivine crystals, confirming that the meteorite was pallasitic.
