Nakano Note (Nakano wa Kangaeru noda) NK 2236 C/2009 S3 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 156 observations 2009 Sept. 24 to 2012 Jan. 15. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.65 arc second. See the previous orbits in NK 1960 and NK 2067 (HICQ 2011/2012). Epoch = 2011 Dec. 25.0 TT T = 2011 Dec. 11.30359 +/- 0.00465 (m.e.)
