Nakano Note (Nakano wa Kangaeru noda) NK 5185 C/2024 B2 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 66 observations 2023 May 14 to 2024 Feb. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.32 arc second. See an orbit in CBET 5345 (same orbit).
