Chug Chug 110 22°29.177’S, 69°11.081’W Antofagasta, Chile Find: 25 Oct 2019 Classification: Ordinary chondrite (LL6) History: The meteorite (1 piece) was found in autumn 2019 by Atali Agakhanov during a meteorite searching expedition organized by Timur Kryachko. Physical characteristics: Total mass is about 350 g. The exterior is dark brown whereas the interior of meteorite is grey-brown with visible metal. Petrography: (Kseniya A. Konovalova, FMMR). Petrographic observation of a polished section shows that the main part of meteorite consist of coarse-middle matrix with very rare chondrules.
