Nakano Note (Nakano wa Kangaeru noda) NK 2596 P/2011 S1 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 95 observations 2010 Sept. 29 to 2013 Nov. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.49 arc second. The recent observations show the residuals of +5" mainly R. A. from an orbit in NK 2464 (HICQ 2013). See the previous orbits in NK 2350 and NK 2464. Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 27.28179 +/- 0.02841 (m.e.)
