Nakano Note (Nakano wa Kangaeru noda) NK 4859 C/2020 K2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 87 observations 2020 May 21 to 2021 June 28. 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. See the previous orbits in CBET 4781 and NK 4220 (= HICQ 2021). Epoch = 2020 Aug. 19.0 TT T = 2020 Aug. 4.64122 +/- 0.02573 (m.e.)
