The following improved orbital elements, by S. Nakano, are from 72 observations 2000 to 2011. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.52 arc second. The planet has been discovered by Spacewatch program in 2006. Also the comet has passed 2.14 AU on 2002 Feb. 13 UT and will pass 1.86 AU on 2041 Mar. 29 UT from Jupiter. H10 seems to be mag.= 13.0.
