The following improved orbital elements, by S. Nakano, are from 212 observations 2019 May 16 to Sept. 21. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. The comet has passed 1.20 AU from Jupiter on 2019 Feb. 22 UT. Epoch = 2020 Feb. 1.0 TT T = 2020 Feb. 12.96549 +/- 0.00177 (m.e.)
