Nakano Note (Nakano wa Kangaeru noda) NK 3165 C/2016 B1 (NEOWISE)
The following improved orbital elements, S. Nakano, are from 68 observations 2016 Jan. 17 to May 15. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. The comet will pass 3.70 AU from Jupiter on 2016 June 25 UT. Epoch = 2016 Nov. 28.0 TT T = 2016 Dec. 4.71844 +/- 0.00644 (m.e.)
