The following improved orbital elements, by S. Nakano, are from 123 observations 2014 Nov. 20 to 2015 Apr. 19. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.57 arc second. The comet has passed 2.60 AU from Jupiter on 2014 Aug. 24 UT. Epoch = 2015 Apr. 8.0 TT T = 2015 Mar. 19.01531 +/- 0.00168 (m.e.)
