Nakano Note (Nakano wa Kangaeru noda) NK 3248 C/2015 R3 (PANSTARRS)

The following improved orbital elements, S. Nakano, are from 32 observations 2015 Sept. 12 to 2016 Sept. 28. 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. Epoch = 2014 Jan. 23.0 TT T = 2014 Feb. 11.75365 +/- 0.01084 (m.e.)
