9700 Paech           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Wolfgang Paech (b. 1951) is an electronic engineer on the staff of the Institute of Geodesy at the University of Hannover, where he serves as technical manager of the astronomical station. An enthusiastic amateur astronomer, Paech is a keen observer of solar phenomena and eclipses. The name was suggested by L. D. Schmadel.
