6795 Örnsköldsvik           Discovered 1993 Mar. 17 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
On the western coast of the Gulf of Bothnia in the Swedish province of \AA ngermanland, Örnsköldsvik is an important center dominated by forestry-related industry. It is the hometown of one of Sweden's most skillful ice-hockey teams, MoDo, where many world-famous players have their roots.
