8040 Utsumikazuhiko           Discovered 1993 Sept. 16 by K. Endate and K. Watanabe at Kitami.
Kazuhiko Utsumi (b. 1937), made the first identification of many of the spectral lines and determined element abundances for carbon stars. At Hiroshima University he has taught astronomy and astrophysics to more than 30~000 students. The name was suggested by Y. Yamada.
