The following improved orbital elements, by S. Nakano, are from 176 observations 1999 to 2015, including planetary perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas, Vesta, and non-gravitational effect of style II. The weighting mean residual is +/- 7.98 arc seconds. The comet was recovered on 2015 May 22 at Cerro Paranal in Chile. See the previous orbits in NK 1537.
