Nakano Note (Nakano wa Kangaeru noda) NK 5232 C/2023 U1 (Fuls)
The following improved orbital elements, by S. Nakano, are from 106 observations 2023 Jan. 24 to 2024 Mar. 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.54 arc second. Residuals for 2024 March observations were -3" for Right Ascension and -5" for Declination from an orbit in NK 5155 (= CH 2024). See the previous orbits in CBET 5308 and NK 5155.
