Nakano Note (Nakano wa Kangaeru noda) NK 4838 P/2021 V2 (Fuls)
The following improved orbital elements, by S. Nakano, are from 156 observations 2021 Aug. 7 to 2022 Oct. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. Residuals for 2022 October observations were -3" mainly for Right Ascension from an orbit in NK 4688. See the previous orbits in CBET 5068, NK 4603, NK 4644, NK 4659 and NK 4688.
