The following improved orbital elements, by S. Nakano, are from 39 observations 1993 May 23 to 1996 Jan. 27. Perturbations by Mercury to Neptune and five minor planets were taken into account. The mean residual is +/- 0.93 arc second. Epoch = 1994 Feb. 17.0 TT T = 1994 Feb. 1.94387 +/- 0.00386 (m.e.)
