Nakano Note (Nakano wa Kangaeru noda) NK 2223 P/2011 C2 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 147 observations 2011 Jan. 30 to 2012 Mar. 21. 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. See previous orbits on HICQ 2011/2012 and NK 2182. Epoch = 2011 Dec. 25.0 TT T = 2012 Jan. 7.51646 +/- 0.02998 (m.e.)
