Nakano Note (Nakano wa Kangaeru noda) NK 4683 C/2021 L3 (Borisov)
The following improved orbital elements, by S. Nakano, are from 160 observations 2021 June 8 to 2022 Mar. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.56 arc second. See the previous orbits in CBET 4985 and NK 4565. Epoch = 2022 Mar. 2.0 TT T = 2022 Feb. 13.83627 +/- 0.13894 (m.e.)
