Nakano Note (Nakano wa Kangaeru noda) NK 3559 C/2017 G3 (PANSTARRS)

The following improved orbital elements, by S. Nakano, are from 141 observations 2017 Apr. 7 to 2018 Jan. 20. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. The comet has passed 3.12 AU from Jupiter on 2017 May 7 and will pass 5.29 AU from Uranus on 2026 Mar. 7 UT. Epoch = 2017 Mar. 28.0 TT T = 2017 Apr. 15.04654 +/- 0.00024 (m.e.)
