The following improved orbital elements, by S. Nakano, are from 81 observations 2024 Jan. 19 to May 4. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second. The comet will pass 3.80 AU from Jupiter on 2025 Aug. 1 UT. See an orbit in CBET 5378. Epoch = 2023 Oct. 23.0 TT T = 2023 Oct. 22.90608 +/- 0.64646 (m.e.)
