The following improved orbital elements, by S. Nakano, are from 61 observations 2000 to 2013. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. Following observations were identified by the author.
