Nakano Note (Nakano wa Kangaeru noda) NK 2508 224P/LINEAR-NEAT
The following improved orbital elements, by T. Kobayashi, are from 90 observations 2003 to 2009. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.50 arc second. See the previous orbits in NK 1119 and NK 1823 (= HICQ 2009/2010). Epoch = 2010 Feb. 13.0 TT T = 2010 Jan. 31.83403 +/- 0.00120 (m.e.)
