5605 Kushida           Discovered 1993 Feb. 17 by S. Otomo at Kiyosato.
Named in honor of Yoshio Kushida (b. 1957), Japanese seismologist. Discoverer of numerous minor planets and comets since 1989, he is also an active confirmer of new objects in collaboration with S. Nakano. He established Yatsugatake South Base Observatory to the benefit of many amateur astronomers.
