Nakano Note (Nakano wa Kangaeru noda) NK 4684 C/2021 Q3 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 145 observations 2021 Aug. 19 to 2022 Mar. 21. 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. See the previous orbits in CBET 5027 and NK 4595. Epoch = 2022 Jan. 21.0 TT T = 2022 Jan. 26.11247 +/- 0.03724 (m.e.)
