The following improved orbital elements, by S. Nakano, are from 76 observations 2002 June 24 to 2003 Oct. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.78 arc second. See an orbit in NK 957 (= HICQ 2004). Epoch = 2001 Nov. 27.0 TT T = 2001 Nov. 23.58452 +/- 0.02820 (m.e.)
