The following improved orbital elements, by S. Nakano, are from 73 observations 1992 Nov. 21 to 1993 Jan. 2. Perturbations by Mercury to Neptune and five minor planets were taken into account. The mean residual is +/- 1.01 arc seconds. Epoch = 1992 Oct. 25.0 TT T = 1992 Nov. 1.59209 +/- 0.00349 (m.e.)
