The following improved orbital elements, by S. Nakano, are from 118 observations 2017 June 23 to Oct. 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. The comet has passed 1.51 AU from Saturn on 2015 Mar. 25 and will pass 2.38 AU from Uranus on 2026 Sept. 4 UT. Epoch = 2018 June 11.0 TT T = 2018 June 2.79346 +/- 0.21387 (m.e.)
