The following improved orbital elements, by S. Nakano, are from 114 observations 2018 June 6 to Oct. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second. The comet has passed 1.84 AU from Jupiter on 2016 Nov. 14 and will pass 5.13 AU from Uranus on 2026 Apr. 13 UT. The observations 2018 June - Aug. 9 were reported on 2022 July MPCs.
