The following improved orbital elements, by S. Nakano, are from 122 observations 2014 Aug. 20 to Dec. 20. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.74 arc second. The comet has passed 3.60 AU from Jupiter on 2014 Dec. 22 UT. Epoch = 2014 Oct. 30.0 TT T = 2014 Oct. 21.51235 +/- 0.00084 (m.e.)
