18473 Kikuchijun           Discovered 1995 Nov. 15 by K. Endate and K. Watanabe at Kitami.
Jun Kikuchi (b. 1967) purchased his first telescope during the height of Halley's Comet fever in 1986. Though cloudy skies thwarted his attempts at comet photography, his interest in solar eclipse photography led him to France in 1999, and to China in 2008 and 2009.
