Nakano Note (Nakano wa Kangaeru noda) NK 3203 P/2012 K3 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 136 observations 2012 May 21 to Sept. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. Epoch = 2012 Sept.30.0 TT T = 2012 Sept.30.33771 +/- 0.00309 (m.e.)
