The following improved orbital elements, by S. Nakano, are from 56 observations 2002 May 16 to Sept. 8. 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. Epoch = 2002 June 15.0 TT T = 2002 June 16.44549 +/- 0.00630 (m.e.)
