Nakano Note (Nakano wa Kangaeru noda) NK 4789 C/2016 KA (Catalina)

The following improved orbital elements, by S. Nakano, are from 79 observations 2016 May 16 to 2017 Apr. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.61 arc second. Later observations from the previous orbit (NK 3239) were reported. Orbit was great improved. Epoch = 2016 Jan. 13.0 TT T = 2016 Feb. 1.22740 +/- 0.02208 (m.e.)
