The following improved orbital elements, by S. Nakano, are from 157 observations 2018 Sept. 5 to 2019 Jan. 8. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.66 arc second. The observations 2018 Sept. and Oct. 6 were reported on 2022 July MPCs. Epoch = 2019 Mar. 18.0 TT T = 2019 Mar. 1.63905 +/- 0.01107 (m.e.)
