Nakano Note (Nakano wa Kangaeru noda) NK 3312 C/2015 J1 (PANSTARRS)
The following improved orbital elements, T. Kobayashi, are from 54 observations 2015 May 14 to 2016 June 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.40 arc second. See the previous orbit in NK 3156 (= HICQ 2016). Epoch = 2014 July 2.0 TT T = 2014 June 29.80396 +/- 0.01182 (m.e.)
