Nakano Note (Nakano wa Kangaeru noda) NK 5155 C/2023 U1 (Fuls)
The following improved orbital elements, by S. Nakano, are from 48 observations 2023 Oct. 16 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 +/- 0.45 arc second. See an orbit in CBET 5308.
