Nakano Note (Nakano wa Kangaeru noda) NK 4895 P/2022 R5 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 42 observations 2022 Sept. 8 to Nov. 24. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. See an orbit in CBET 5175.
