Nakano Note (Nakano wa Kangaeru noda) NK 2067 C/2009 S3 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 71 observations 2009 Sept. 24 to 2011 Apr. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.52 arc second. See an orbit in NK 1960 (= HICQ 2010/2011).
