Named in honor of Toshiyuki Minowa (1918– ), a Japanese amateur astronomer. During ten years beginning in 1949, a meteor camera of the Tokyo Astronomical Observatory was installed in his garden as the end of a baseline. He was one of the founders, in 1953, of Kawasaki Astronomy Club. As a schoolmaster, he was eager to popularize astronomy among children, and he contributed a telescope that can be operated by a wheelchair user. He was the second chairman of the Japan Amateur Astronomers’ Convention (1980–1983). (M 29148) _ _.
