Nakano Note (Nakano wa Kangaeru noda) NK 2186 C/2011 UF305 (LINEAR)
The following improved orbital elements, by S. Nakano, are from 97 observations 2011 July 25 to Dec. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second. The comet will pass 3.21 AU from Jupiter on 2013 Apr. 29 UT. Epoch = 2012 July 12.0 TT T = 2012 July 22.12113 +/- 0.01074 (m.e.)
