Nakano, are from 64 observations 2003 to 2014. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.54 arc second. The residuals of 2003 observations from the latest orbit were -0.06 deg for R. A. and -0.02 deg for Declination with the delta-T correction = -0.17 day.
