Nakano Note (Nakano wa Kangaeru noda) NK 4647 C/2022 A3 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 104 observations 2021 Apr. 30 to 2022 Mar. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.37 arc second. See an orbit in CBET 5106 (same orbit).
