The following improved orbital elements, by S. Nakano, are from 117 observations 1994 May 14 to Sept. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.73 arc second. See an orbit on MPC 25313. This is a revised orbit. Epoch = 1994 Oct. 15.0 TT T = 1994 Oct. 14.59838 +/- 0.01321 (m.e.)
