Nakano Note (Nakano wa Kangaeru noda) NK 4897 P/2022 S1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 64 observations 2022 Sept. 14 to Nov. 24. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.30 arc second. See an orbit in CBET 5176. Epoch = 2022 Aug. 9.0 TT T = 2022 Aug. 19.18241 +/- 0.04007 (m.e.)
