Nakano Note (Nakano wa Kangaeru noda) NK 4047 A/2019 U6
The following improved orbital elements, by S. Nakano, are from 82 observations 2018 Nov. 6 to 2020 Feb. 5. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second.
