Nakano Note (Nakano wa Kangaeru noda) NK 4059 A/2019 S4
The following improved orbital elements, by S. Nakano, are from 71 observations 2019 Sept. 17 to 2020 Feb. 20. 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. See an orbit in HICQ 2020.
