Nakano Note (Nakano wa Kangaeru noda) NK 3509 C/2016 E1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 91 observations 2016 Mar. 3 to 2017 May 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.33 arc second. The comet has passed 0.62 AU from Saturn on 2014 Nov. 14 and 4.34 AU from Jupiter on 2017 Feb. 20 UT. See the previous orbits in HICQ 2017 and NK 3353.
