Nakano Note (Nakano wa Kangaeru noda) NK 5184 C/2024 B1 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 53 observations 2023 Oct. 13 to 2024 Feb. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. See an orbit in CBET 5344 (same orbit).
