5879 Almeria           Discovered 1992 Feb. 8 by K. Birkle and U. Hopp at Calar Alto.
Named for the Spanish city and province where the Calar Alto Observatory of the German-Spanish Astronomical Center is located. The observatory is operated jointly by the Max-Planck-Institut für Astronomie in Heidelberg and the Spanish National Commission for Astronomy. The naming acknowledges the great Spanish hospitality experienced by German astronomers at the observatory.
