Nakano Note (Nakano wa Kangaeru noda) NK 5622 C/2026 M5 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 54 observations 2025 Sept. 18 to 2026 Aug. 12. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.41 arc second. See an orbit in CBET 5720.
