Nakano Note (Nakano wa Kangaeru noda) NK 2071 C/2010 R1 (LINEAR)
The following improved orbital elements, by S. Nakano, are from 60 observations 2010 Sept. 4 to 2011 Apr. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.66 arc second. The comet has passed 3.02 AU from Uranus on 2004 Nov. 1 UT. See an orbit on HICQ 2010/2011. Epoch = 2012 June 2.0 TT T = 2012 May 18.68324 +/- 0.13412 (m.e.)
