Nakano Note (Nakano wa Kangaeru noda) NK 3101 C/2015 J2 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 83 observations 2015 Mar. 21 to 2016 Apr. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. Residuals of 2016 April observations were +3" mainly for Right Ascension from an orbit in NK 3002. Epoch = 2015 Sept.15.0 TT T = 2015 Sept. 8.90491 +/- 0.00562 (m.e.)
