Nakano Note (Nakano wa Kangaeru noda) NK 4019 A/2019 O2
The following improved orbital elements, by S. Nakano, are from 55 observations 2019 July 24 to Nov. 24. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.27 arc second.
