Nakano Note (Nakano wa Kangaeru noda) NK 3955 C/2019 E3 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 61 observations 2015 Jan. 22 to 2019 Nov. 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.43 arc second. Epoch = 2023 Dec. 2.0 TT T = 2023 Nov. 15.26145 +/- 0.03336 (m.e.)
