Nakano Note (Nakano wa Kangaeru noda) NK 4697 P/2011 S1 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 143 observations 2010 Sept. 29 to 2019 Jan. 2. 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. Three observations (mag.= 23) on 2018/2019 at W84 are located within +/-0".5 from an orbit in NK 3037 (= HICQ 2016). See the previous orbits in NK 2350, NK 2464, NK 2596, NK 2790 and NK 3037.
