Nakano Note (Nakano wa Kangaeru noda) NK 2790 P/2011 S1 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 105 observations 2010 Sept. 29 to 2014 Oct. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.50 arc second. See the previous orbits in NK 2350, NK 2464 and NK 2596 (= HICQ 2014). Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 27.35874 +/- 0.01134 (m.e.)
