Nakano Note (Nakano wa Kangaeru noda) NK 4020 A/2019 O3
The following improved orbital elements, by S. Nakano, are from 80 observations 2019 May 14 to Dec. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.40 arc second. Epoch = 2021 Mar. 7.0 TT T = 2021 Mar. 8.23880 +/- 0.20835 (m.e.)
