Nakano Note (Nakano wa Kangaeru noda) NK 4096 C/2016 Q2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 149 observations 2016 Aug. 26 to 2020 Apr. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second.
