Nakano Note (Nakano wa Kangaeru noda) NK 5274 C/2024 L2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 30 observations 2023 July 15 to 2024 July 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second. See an orbit in CBET 5405.
