Nakano Note (Nakano wa Kangaeru noda) NK 2013 C/2010 FB87 (WISE-Garradd)
The following improved orbital elements, by S. Nakano, are from 68 observations 2010 Mar. 28 to Nov. 10. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.50 arc second. The comet will pass 2.96 AU from Jupiter on 2012 Nov. 16 UT. Epoch = 2010 Nov. 20.0 TT T = 2010 Nov. 7.38495 +/- 0.00393 (m.e.)
