Nakano Note (Nakano wa Kangaeru noda) NK 5022 302P/Lemmon-PANSTARRS
The following improved orbital elements, by S. Nakano, are from 189 observations 2007 to 2023. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. See the previous orbits in NK 2694, NK 3230 and NK 3720. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 9.41888 +/- 0.00030 (m.e.)
