Nakano Note (Nakano wa Kangaeru noda) NK 5156 C/2023 V1 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 69 observations 2023 Aug. 2 to Dec. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.30 arc second. The comet has passed 5.13 AU from Uranus on 2017 July 9 UT. See the previous orbits in CBET 5311 and NK 5124. Epoch = 2025 July 24.0 TT T = 2025 July 13.04361 +/- 0.01097 (m.e.)
