Nakano Note (Nakano wa Kangaeru noda) NK 5385 P/2024 T1 (Rankin)
The following improved orbital elements, by S. Nakano, are from 153 observations 2024 Sept. 9 to 2025 Feb. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.51 arc second. See the previous orbits in CBET 5455 and NK 5357. Epoch = 2024 Oct. 17.0 TT T = 2024 Sept.30.47259 +/- 0.00151 (m.e.)
