6867 Kuwano           Discovered 1992 Mar. 28 by K. Endate and K. Watanabe at Kitami.
Named in memory of Yoshiyuki Kuwano (1931-1998), librarian and later director of Hita Municipal Tanso Memorial Library, Oita Prefecture. As an amateur astronomer, he discovered five novae (IV Cep, V3888 Sgr, V3889 Sgr, V2104 Oph, V4021 Sgr) and the peculiar variable PU Vul. An organizer and leader of local amateur astronomers, he actively popularized astronomy to the public through his frequent lectures and star parties. Name proposed by the discoverers following a suggestion by T. Funada, T. Sato and A. Fujii.
