15350 Naganuma           Discovered 1994 Nov. 3 by Y. Kushida and O. Muramatsu at the Yatsugatake South Base Observatory.
Naganuma, Hokkaido, has for many years promoted the arts at the "Artists Atelier Village", with more than 20 workshops. The Naganuma Library has sponsored an exhibition of cloisonne works by N. Iizawa to commemorate the 250th anniversary of the birth of Caroline Herschel. The name was suggested by S. Kimura.
