Nakano Note (Nakano wa Kangaeru noda) NK 3960 C/2019 T3 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 107 observations 2019 Jan. 17 to Dec. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. The comet will pass 3.31 AU from Jupiter on 2022 Mar. 26 and 2.29 AU from Saturn on 2023 June 3 UT. See the previous orbit in NK 3930.
