The following improved orbital elements, by S. Nakano, are from 68 observations 2002 June 24 to 2003 Aug. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.80 arc second. Epoch = 2001 Nov. 27.0 TT T = 2001 Nov. 23.59678 +/- 0.03812 (m.e.)
