6654 Luleå           Discovered 1992 Feb. 29 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
Luleå, a center of the steel industry on the northwestern coast of the Gulf of Bothnia and capital of the Swedish province of Norrbotten, dates back to the fourteenth century as a center for trade between the inland Samis and the population of southern Sweden.
