Nakano Note (Nakano wa Kangaeru noda) NK 5117 P/2023 M2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 108 observations 2023 June 22 to Oct. 31. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.51 arc second. See an orbit in CBET 5276.
