The following improved orbital elements, by S. Nakano, are from 156 observations 2010 to 2022. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. An orbit from 2022 observations (until Nov. 15) shows the residuals of -0.15 deg for Right Ascension and -0.22 deg for Declination with the delta-T correction = -0.81 day. Epoch = 2023 Feb. 25.0 TT T = 2023 Mar. 3.04773 +/- 0.02927 (m.e.)
