The Vyatka meteorite was discovered in the Kirov region of Russia in 1992 when a large mass was found on the banks of Vyatka river near the town of Sovetsk. It was analyzed and confirmed to be a H4 chondrite. Specimens of this meteorite have also been sold to collectors under the name "Kaigorod".

Vyatka, location of main mass
A 32 kg piece of a larger stone was purchased by S. Vassiliev in Prague. The meteorite was reportedly found in the Kirov region of Russia and is undoubtedly the missing main mass of Vyatka, an H4 chondrite (see Meteoritical Bulletin 77; Wlotzka, 1994). This material is widely distributed in collections outside of Russia under the name "Kaigorod," which will now become a synonym for Vyatka. Classification and description of "Kaigorod" (J. Otto, Frei): an H4/5 chondrite; olivine, Fa17.1; pyroxene, Fs15.5Wo0.9; shock stage, S3; weathering grade, W1. Comparison of Vyatka and "Kaigorod" (M. Ivanova and A. Skripnik, Vernad): texture, shock stage, mineral chemistry, and petrologic type all similar; Vyatka somewhat more weathered. Specimens: main mass, ~10 kg, Vass; 9.4 g, Frei.
