Nakano Note (Nakano wa Kangaeru noda) NK 4062 A/2019 U6
The following improved orbital elements, by S. Nakano, are from 147 observations 2018 Nov. 6 to 2020 Mar. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.42 arc second. Some observers report comet nature and visual mag.= 13 on middle March of this object. See the previous orbits in NK 4025 (= HICQ 2020) and NK 4047.
