Nakano Note (Nakano wa Kangaeru noda) NK 5477 C/2025 M1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 80 observations 2021 May 18 to 2025 July 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.47 arc second. See an orbit in CBET 5575 (= NK 5418).
