Nakano Note (Nakano wa Kangaeru noda) NK 2717 234P/LINEAR
The following improved orbital elements, by T. Kobayashi, are from 146 observations 2001 to 2010. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.63 arc second. See the previous orbits in NK 1893 (= HICQ 2010). Epoch = 2010 Jan. 4.0 TT T = 2009 Dec. 23.70390 +/- 0.00626 (m.e.)
