8410 Hiroakiohno           Discovered 1996 Aug. 24 by S. Ueda and H. Kaneda at Kushiro.
Hiroaki Ohno (b. 1948), director of Hoshinomura Observatory in Fukushima prefecture, is also a member of Shirakawa Observatory in Japan and Chiro Observatory in Australia. He is well known for his astrophotography and greatly contributes to the popularization of astronomy by frequent television and radio appearances.
