47077 Yuji           Discovered 1998 Dec. 16 by A. Nakamura at Kuma Kogen.
Yuji Nakamura (b. 1956) is an amateur astronomer and chemical engineer at the municipal office of Yokkaichi City. During his 32-year visual search for comets, Nakamura discovered C/1990 E1 and rediscovered 122P/1995 S1 (de Vico). Also an enthusiastic nova hunter since 2001, he has discovered three novae.
