Nakano Note (Nakano wa Kangaeru noda) NK 4883 C/2022 H1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 62 observations 2022 Mar. 2 to Aug. 1. 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 5120.
