8526 Takeuchiyukou           Discovered 1992 Sept. 23 by K. Endate and K. Watanabe at Kitami.
Yukou Takeuchi (b. 1932), Japanese amateur astronomer, designed a quartet camera system with a rotating shutter to measure the velocity of meteors, a system that he later improved to be automatic. In 1990 he began video observation with an image intensifier.
