Nakano Note (Nakano wa Kangaeru noda) NK 2781 C/2013 G8 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 133 observations 2013 Apr. 14 to 2014 Sept. 16. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.42 arc second.
