The following improved orbital elements, by S. Nakano, are from 105 observations 2016 Mar. 6 to May 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.73 arc second. The comet has passed 3.99 AU from Jupiter on 2016 Apr. 28 UT. Outside observations from the previous orbit were reported. Epoch = 2016 Feb. 22.0 TT T = 2016 Feb. 6.67724 +/- 0.01040 (m.e.)
