Nakano Note (Nakano wa Kangaeru noda) NK 2196 C/2011 J2 (LINEAR)
The following improved orbital elements, by S. Nakano, are from 124 observations 2011 Mar. 10 to 2012 Feb. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The comet has passed 4.03 AU from Saturn on 2010 Nov. 22 and will pass 4.09 AU from Jupiter on 2013 Sept. 13 UT. The mean residual is +/- 0.52 arc second. See an orbit on HICQ 2011/ 2012.
