6458 Nouda           Discovered 1992 Oct. 2 by T. Seki at Geisei.
Named in memory of Tadasuke Nouda (1901-1989), Japanese astronomer. A pioneer in the field of ancient Chinese astronomy, he made important contributions to the study of early luni-solar calendars. He was a professor at the Osaka University of Education and Kyoto Sangyo University. He served as president of the Japan Calendar Association (1959-1989) and of the Oriental Astronomical Association (1965-1989). Name proposed by the discoverer following a suggestion by I. Hasegawa and T. Sato. Citation by I. Hasegawa.
