Nakano Note (Nakano wa Kangaeru noda) NK 2277 C/2011 KP36 (Spacewatch)
The following improved orbital elements, by S. Nakano, are from 102 observations 2011 May 21 to 2012 June 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.33 arc second. The previous return would be around 1778. Epoch = 2016 May 12.0 TT T = 2016 May 28.18058 +/- 0.21045 (m.e.)
