11970 Palitzsch           Discovered 1994 Oct. 4 by P. Sicoli and P. Ghezzi at Sormano.
Johann Georg Palitzsch (1723-1788) was a farmer by profession and an astronomer by vocation. He recovered comet 1P/Halley on its first predicted return in 1758 and observed further comets, as well as variable stars such as Mira and Algol. The citation was prepared by P. Brosche.
