10962 Sonnenborgh           Discovered 1960 Oct. 17 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
The astronomical observatory Sonnenborgh in Utrecht, founded in 1853 by Buys Ballot, specializes in the study of the sun. In 1988, when the Institute moved to a new building, Sonnenborgh became a public observatory and now houses the "Stichting De Koepel", a school of astronomy.
