Nakano Note (Nakano wa Kangaeru noda) NK 4126 A/2019 U5
The following improved orbital elements, by S. Nakano, are from 82 observations 2019 Oct. 11 to 2020 May 29. 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. See the previous orbits in HICQ 2020 and NK 4084. Epoch = 2023 Apr. 6.0 TT T = 2023 Mar. 29.80144 +/- 0.03831 (m.e.)
