10064 Hirosetamotsu           Discovered 1988 Oct. 31 by T. Kojima at Chiyoda.
Tamotsu Hirose (b. 1931) is known as an astronomical leader throughout the four prefectures of the island of Shikoku. He began observing sunspots with a heliostat in 1949, after which he built his own private observatory for the continuous observation of sunspots, a major contribution to astronomy.
