Nakano Note (Nakano wa Kangaeru noda) NK 5215 C/2024 G5 (Leonard)
The following improved orbital elements, by S. Nakano, are from 92 observations 2023 Dec. 15 to 2024 May 5. 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 5391 (same orbit).
