Nakano Note (Nakano wa Kangaeru noda) NK 2582 P/2013 O2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 135 observations 2013 July 16 to Nov. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.63 arc second. Epoch = 2013 Dec. 14.0 TT T = 2013 Dec. 16.37758 +/- 0.00444 (m.e.)
