Nakano Note (Nakano wa Kangaeru noda) NK 2107 C/2010 R1 (LINEAR)
The following improved orbital elements, by S. Nakano, are from 130 observations 2010 Sept. 4 to 2011 July 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.62 arc second. The comet has passed 3.01 AU from Uranus on 2004 Oct. 31 UT. The RunOff from NK 2071 (= HICQ 2011/2012) was extreme large which were -19" for R. A. and +3" for Decl. on 2011 July 2 observation.
