The following improved orbital elements, by S. Nakano, are from 58 observations 2022 May 9 to Nov. 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.46 arc second. The comet will pass 1.93 AU from Jupiter on 2023 Aug. 12 and 4.54 AU from Saturn on 2025 Apr. 17 UT. See an orbit in CBET 5143. Epoch = 2022 Oct. 28.0 TT T = 2022 Oct. 27.05779 +/- 0.00255 (m.e.)
