The following improved orbital elements, T. Kobayashi, are from 131 observations 2014 Nov. 20 to 2015 July 20. 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 2.60 AU from Jupiter on 2014 Aug. 24 UT. See the previous orbits in NK 2910 and NK 2973 (= HICQ 2015). Epoch = 2015 Apr. 8.0 TT T = 2015 Mar. 19.01146 +/- 0.00200 (m.e.)
