Nakano Note (Nakano wa Kangaeru noda) NK 4084 A/2019 U5
The following improved orbital elements, by S. Nakano, are from 49 observations 2019 Oct. 11 to 2020 Mar. 22. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.22 arc second. See an orbit in HICQ 2020.
