The first Muonionalusta meteorite, from the north of the Artic circle in the uppermost region of Sweden (Coordinates 67*48’N/23*6′ E), was discovered in 1906 by Viktor Mattila and his sister Amalia Mattila. In subsequent years other Muonionalustas have been found in the region as well. The largest specimen, weighing 15 kg, was found in 1946.
The Muonionalusta is an iron meteorite classified as a fine octahedrite. An interesting feature of this meteorite is the Widmanstätten-pattern.
