Nakano Note (Nakano wa Kangaeru noda) NK 2526 237P/LINEAR
The following improved orbital elements, by T. Kobayashi, are from 106 observations 2002 to 2011. 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. See the previous orbit in NK 1946 (= HICQ 2010/2011). Epoch = 2009 Nov. 25.0 TT T = 2009 Dec. 2.77384 +/- 0.00093 (m.e.)
