Nakano Note (Nakano wa Kangaeru noda) NK 5157 P/2023 V2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 70 observations 2023 Sept. 19 to 2024 Jan. 11. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.18 arc second. See an orbit in CBET 5312. Epoch = 2024 Feb. 20.0 TT T = 2024 Feb. 4.17190 +/- 0.00707 (m.e.)
