Nakano Note (Nakano wa Kangaeru noda) NK 4872 C/2021 Q3 (ATLAS)

The following improved orbital elements, by S. Nakano, are from 151 observations 2021 Aug. 19 to 2022 Nov. 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. Residuals for 2022 October/November observations were +4" mainly for Declination from an orbit in NK 4684. See the previous orbits in CBET 5027, NK 4595 and NK 4684.
