Nakano Note (Nakano wa Kangaeru noda) NK 2671 C/2013 B2 (Catalina)
The following improved orbital elements, by S. Nakano, are from 131 observations 2013 Jan. 16 to 2014 Mar. 30. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second. The comet has passed 3.65 AU from Jupiter on 2013 Feb. 14 UT. See the previous orbits in HICQ 2013 and NK 2577. Epoch = 2013 July 7.0 TT T = 2013 July 1.54262 +/- 0.00139 (m.e.)
