The following improved orbital elements, by S. Nakano, are from 388 observations 2023 Aug. 13 to Aug. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. Period is still uncertainty about +/- 50 years or more. See an orbit in CBET 5285. Ehemerides are show below. Epoch = 1899 Nov. 30.0 TT T = 2023 Sept.17.64135 +/- 0.00133 (m.e.)
