Nakano Note (Nakano wa Kangaeru noda) NK 4224 C/2020 N1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 134 observations 2020 July 1 to Sept. 21. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.46 arc second. See an orbit in CBET 4815.
