Nakano Note (Nakano wa Kangaeru noda) NK 4391 C/2020 U5 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 109 observations 2020 Sept. 25 to 2021 Jan. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second. See an orbit in CBET 4881.
