The following improved orbital elements, by S. Nakano, are from 180 observations 2019 Aug. 10 to 2020 July 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.38 arc second. See an orbit in CBET 4814 (same orbit).
