Nakano Note (Nakano wa Kangaeru noda) NK 4025 A/2019 U6
The following improved orbital elements, by S. Nakano, are from 49 observations 2018 Nov. 6 to 2019 Dec. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.29 arc second. Epoch = 2020 May 31.0 TT T = 2020 June 18.82396 +/- 0.00251 (m.e.)
