Nakano Note (Nakano wa Kangaeru noda) NK 5384 P/2024 S2 (Rankin)
The following improved orbital elements, by S. Nakano, are from 156 observations 2024 Sept. 30 to Dec. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. See an orbit in CBET 5456.
