The following improved orbital elements, by T. Kobayashi, are from 235 observations 1986 to 2014. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.69 arc second. The comet has passed 0.27 AU from Jupiter on 2015 Nov. 4 UT. See the previous orbits in NK 650, NK 946, NK 1912 and NK 2538. Epoch = 2013 Aug. 16.0 TT T = 2013 July 28.46695 +/- 0.00011 (m.e.)
