Nakano Note (Nakano wa Kangaeru noda) NK 2468 C/2010 U3 (Boattini)
The following improved orbital elements, by S. Nakano, are from 171 observations 2010 Oct. 31 to 2013 Feb. 8. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.68 arc second. See the previous orbits in NK 2113 and NK 2334. Epoch = 2019 Mar. 18.0 TT T = 2019 Feb. 26.73025 +/- 0.10853 (m.e.)
