Nakano Note (Nakano wa Kangaeru noda) NK 4870 C/2021 L3 (Borisov)
The following improved orbital elements, by S. Nakano, are from 173 observations 2021 June 8 to 2022 Oct. 13. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. See the previous orbits in CBET 4985, NK 4565 and NK 4683. Epoch = 2022 Mar. 2.0 TT T = 2022 Feb. 13.65071 +/- 0.02106 (m.e.)
