Nakano Note (Nakano wa Kangaeru noda) NK 3175 C/2015 H2 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 74 observations 2015 Apr. 20 to 2016 July 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.41 arc second.
