The following improved orbital elements, by S. Nakano, are from 241 observations 2010 Oct. 31 to 2014 Feb. 22. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.68 arc second. See the previous orbits in NK 2113, NK 2334 and NK 2468 (= HICQ 2013). Epoch = 2019 Mar. 18.0 TT T = 2019 Feb. 26.63888 +/- 0.02918 (m.e.)
