The following improved orbital elements, by S. Nakano, are from 98 observations 1996 to 2011. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. The identifications were found by T. Spahr and an observation on 1996 Sept. 14 was found by M. Meyer. Epoch = 2011 Feb. 8.0 TT T = 2011 Feb. 8.73551 +/- 0.00087 (m.e.)
