Nakano Note (Nakano wa Kangaeru noda) NK 5623 P/2026 N2
The following improved orbital elements, by S. Nakano, are from 80 observations 2021 to 2026. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.23 arc second. See an orbit in CBET 5726 (same orbit). Epoch = 2026 Oct. 7.0 TT T = 2026 Sept.25.77309 +/- 0.00685 (m.e.)
