(10558) Karlstad Main-belt Asteroid
Discovered on 15 September 1993 by E. W. Elst at La Silla.
Karlstad, the capital of Värmland, lies in southwest-central Sweden, on the northern shore of Lake Vänern. In 1865 the city was almost completely destroyed by fire. It was rebuilt along modern lines, with broad avenues and large parks. Karlstad's economy is based on forest products and heavy machinery.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
