11673 Baur           Discovered 1998 Jan. 26 at Farra d´Isonzo.
German amateur astronomer Johann M. Baur (b. 1930) founded the Chaonis Observatory in northern Italy and there discovered many minor planets by means of photographic plates. The telescope he used to make his first discovery is still in use at the Farra Observatory.
