Nakano Note (Nakano wa Kangaeru noda) NK 3331 C/2016 B1 (NEOWISE)
The following improved orbital elements, S. Nakano, are from 108 observations 2016 Jan. 17 to Aug. 23. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.45 arc second. The comet has passed 3.70 AU from Jupiter on 2016 June 25 UT. See the previous orbit in NK 3165. Epoch = 2016 Nov. 28.0 TT T = 2016 Dec. 4.72290 +/- 0.00124 (m.e.)
