1991 SM1. Discovered 1991 Sept. 30 by K. Endate and K. Watanabe at Kitami.

Named in memory of Katsue Misawa (1885-1937). Although he received only a limited education, through his own efforts he became a junior-high-school geography teacher. His unique teaching practices are highly appreciated in the history of Japanese education. In astronomy, he was the real pioneer of sunspot observation in Japan, systematically observing sunspots from 1921 until 1934, when failing eyesight prevented it. His data were invaluable because in those days foreign data arrived in Japan only after a long delay. (M 34342)

Name proposed by the discoverers following a suggestion by K. Gomi, T. Sato, K. Fujimori and A. Fujii.
