Comet P/2000 Y10 (Mueller 4)
Abstract
S. Nakano, Sumoto, Japan, reports the recovery of P/1992 G3 (= 1992g = 1992 IV) by T. Oribe (Saji Observatory) on CCD images taken with a 1.03-m reflector, with the astrometry given below. The comet is faint and of stellar appearance on 2000 Dec. 22 (m_2 = 20.5). The indicated correction to the orbital elements on MPC 31663 (ephemeris on MPC 41213) is Delta(T) = +0.23 day. 2000/01 UT R.A.
