Nakano Note (Nakano wa Kangaeru noda) NK 5064 P/2023 H3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 57 observations 2023 Mar. 16 to June 13. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.28 arc second. See an orbit in CBET 5267. Epoch = 2024 Feb. 20.0 TT T = 2024 Feb. 18.71447 +/- 0.12510 (m.e.)
