Nakano Note (Nakano wa Kangaeru noda) NK 5007 P/PANSTARRS (2014 OL465)
The following improved orbital elements, by S. Nakano, are from 82 observations 2012 to 2023. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.41 arc seconds. See an orbit in CBET 5262 (same orbit). Epoch = 2023 Feb. 25.0 TT T = 2023 Feb. 28.23180 +/- 0.00060 (m.e.)
