The following improved orbital elements, by S. Nakano, are from 87 observations 2022 May 30 to Sept. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.40 arc second. The comet has passed 3.41 AU from Jupiter on 2022 Aug. 18 and will pass 4.84 AU from Saturn on 2023 Apr. 20 UT. See an orbit in CBET 5127.
