The following improved orbital elements, by S. Nakano, are from 71 observations 1985-1994. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.94 arc second. Epoch = 1994 Mar. 29.0 TT T = 1994 Mar. 18.72145 +/- 0.00079 (m.e.)
