The following improved orbital elements, by S. Nakano, are from 157 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 +/- 0.57 arc second. The identifications were found by T. Spahr and an observation on 1996 Sept. 14 was found by M. Meyer. See a previous orbit in NK 2026 (= HICQ 2011/2012). Epoch = 2011 Feb. 8.0 TT T = 2011 Feb. 8.73706 +/- 0.00052 (m.e.)
