Nakano Note (Nakano wa Kangaeru noda) NK 3992 C/2019 T4 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 29 observations 2019 Feb. 5 to Nov. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second.
