The following improved orbital elements, by S. Nakano, are from 106 observations 2012 May 30 to Oct. 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 19.26724 +/- 0.07530 (m.e.)
