Nakano Note (Nakano wa Kangaeru noda) NK 3586 C/2017 AB5 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 69 observations 2017 Jan. 3 to 2018 Apr. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. See the previous orbit in NK 3552.
