11916 Wiesloch           Discovered 1992 Sept. 24 by L. D. Schmadel and F. Borngen at Tautenburg.
The city of Wiesloch celebrates the 1200th anniversary of its first documented mention in mid-2001. Situated some 16 km south of the famous Heidelberg-Königstuhl Observatory, it became the home town of the first discoverer more than 30 years ago.
