Nakano Note (Nakano wa Kangaeru noda) NK 3236 P/PANSTARRS (2016 SV = 2009 Q9)
The following improved orbital elements, by S. Nakano, are from 53 observations 2009 to 2016. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. Epoch = 2016 Sept. 9.0 TT T = 2016 Sept.11.38904 +/- 0.00380 (m.e.)
