Nakano Note (Nakano wa Kangaeru noda) NK 5124 C/2023 V1 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 53 observations 2023 Aug. 2 to Nov. 17. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.26 arc second. The comet has passed 5.12 AU from Uranus on 2017 July 9 UT. See an orbit in CBET 5311. Epoch = 2025 July 24.0 TT T = 2025 July 13.03674 +/- 0.01983 (m.e.)
