Nakano Note (Nakano wa Kangaeru noda) NK 5191 C/2023 X7 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 69 observations 2023 Dec. 10 to 2024 Feb. 20. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.37 arc second. The comet will pass 2.17 AU from Jupiter on 2025 Aug. 26 UT. See an orbit in CBET 5355 (same orbit). Epoch = 2025 May 5.0 TT T = 2025 May 15.17903 +/- 0.01507 (m.e.)
