Nakano Note (Nakano wa Kangaeru noda) NK 5299 C/2023 V1 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 85 observations 2022 Sept. 23 to 2024 Aug. 30. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.32 arc second. 2024 August observations show the residuals of +2" mainly for Right Ascension from an orbit in NK 5156 (= CH 2024). The comet has passed 5.13 AU from Uranus on 2017 July 9 UT. See the previous orbits in CBET 5311, NK 5124 and NK 5156. Epoch = 2025 July 24.0 TT T = 2025 July 13.05120 +/- 0.00360 (m.e.)
