Nakano Note (Nakano wa Kangaeru noda) NK 4856 P/2019 V2 (Groeller)
The following improved orbital elements, by S. Nakano, are from 116 observations 2019 Nov. 3 to 2022 June 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. See the previous orbits in NK 4064 (= HICQ 2021) and NK 4453. Epoch = 2020 Nov. 7.0 TT T = 2020 Oct. 20.07442 +/- 0.00323 (m.e.)
