Nakano Note (Nakano wa Kangaeru noda) NK 5325 P/2024 OC2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 37 observations 2024 July 9 to Nov. 12. 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 5473 (same orbit). Epoch = 2024 Oct. 17.0 TT T = 2024 Oct. 9.32744 +/- 0.00015 (m.e.)
