Tsuchikawa and O. Muramatsu at the Yanagida Observatory. Yanagida village is located in the center of Noto peninsula. This village is home of the Yanagida Astronomical Observatory, where this minor planet was discovered. In Mar. 2005, Yanagida village and two neighboring towns, Noto and Uchiura, will be combined to form a new town.
