The following improved orbital elements, by S. Nakano, are from 154 observations 1992 Apr. 1 to 1993 Jan. 23. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.89 arc second. Epoch = 1992 Apr. 8.0 TT T = 1992 Apr. 22.69017 +/- 0.00035 (m.e.)
