Nakano Note (Nakano wa Kangaeru noda) NK 4533 C/2020 R2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 194 observations 2020 Aug. 18 to 2021 Sept. 17. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.47 arc second.
