Nakano Note (Nakano wa Kangaeru noda) NK 2566 P/2013 CU129 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 125 observations 2013 Feb. 1 to Sept. 8. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.51 arc second. Epoch = 2013 Aug. 16.0 TT T = 2013 Aug. 6.93220 +/- 0.00003 (m.e.)
