The following improved orbital elements, by S. Nakano, are from 88 observations 1994 Mar. 14 to Sept. 13. Perturbations by Mercury to Neptune and five minor planets were taken into account. The mean residual is +/- 0.78 arc second. See an orbit on MPC 25182. Epoch = 1994 May 8.0 TT T = 1994 May 27.45898 +/- 0.00026 (m.e.)
