Nakano Note (Nakano wa Kangaeru noda) NK 4659 P/2021 V2 (Fuls)
The following improved orbital elements, by S. Nakano, are from 110 observations 2021 Aug. 7 to 2022 Mar. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.33 arc second. See the previous orbits in CBET 5068, NK 4603 and NK 4644. Epoch = 2023 Jan. 16.0 TT T = 2023 Jan. 21.41463 +/- 0.00482 (m.e.)
