(7442) Inouehideo Main-belt Asteroid

Discovered on 20 September 1995 by Endate, K., Watanabe, K. at Kitami.

Named in honor of Hideo Inoue (b. 1917), Japanese astronomer. An astronomy enthusiast while still a child, he studied at the Tokyo College of Physics and at the Institute of Cosmical Physics in Kyoto. While participating in Kyoto University's expedition to the total solar eclipse on 1941 Sept. 21 he obtained color photographs of the solar corona, the first in Japan. He later worked at the Peking Observatory, where he calculated the national ephemeris. After the war he taught at technical high schools in Japan. For the International Geophysical Year he led the Higasimatuyama Moonwatch Team. He is also an enthusiastic ham radio operator.Naming citation (19990402/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
