Nakano Note (Nakano wa Kangaeru noda) NK 2113 C/2010 U3 (Boattini)
The following improved orbital elements, by S. Nakano, are from 105 observations 2010 Oct. 31 to 2011 July 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.65 arc second. See an orbit on HICQ 2011/2012.
