The following improved orbital elements, by T. Kobayashi, are from 116 observations 2000 to 2009. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.75 arc second. See the previous orbits in NK 802 and NK 1694 (= YC 2600). Epoch = 2008 Oct. 21.0 TT T = 2008 Nov. 6.25517 +/- 0.00004 (m.e.)
