Nakano Note (Nakano wa Kangaeru noda) NK 3264 C/2015 H2 (PANSTARRS)

The following improved orbital elements, S. Nakano, are from 89 observations 2015 Apr. 20 to 2016 Nov. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.38 arc second. See the previous orbits in NK 3084 (= HICQ 2016) and NK 3175. Epoch = 2016 Sept. 9.0 TT T = 2016 Sept.13.26610 +/- 0.00377 (m.e.)
