Nakano Note (Nakano wa Kangaeru noda) NK 4928 P/2022 S1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 75 observations 2022 Sept. 14 to 2023 Jan. 24. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.30 arc second. See the previous orbits in CBET 5176 and NK 4897. Epoch = 2022 Aug. 9.0 TT T = 2022 Aug. 19.03629 +/- 0.01326 (m.e.)
