Nakano Note (Nakano wa Kangaeru noda) NK 4784 C/2015 R3 (PANSTARRS)

The following improved orbital elements, by S. Nakano, are from 40 observations 2013 Mar. 5 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 +/- 0.56 arc second. Past observations 2013 - 2015 Jan. from the previous orbit (NK 3248) were reported. Orbit was great improved. Epoch = 2014 Jan. 23.0 TT T = 2014 Feb. 11.81140 +/- 0.00389 (m.e.)
