The following improved orbital elements, by S. Nakano, are from 129 observations 2018 June 8 to Sept. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second. Epoch = 2018 May 2.0 TT T = 2018 May 4.47685 +/- 0.00729 (m.e.)
