Nakano Note (Nakano wa Kangaeru noda) NK 2660 C/2010 L3 (Catalina)
The following improved orbital elements, by S. Nakano, are from 123 observations 2010 June 15 to 2013 Apr. 8. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.56 arc second. The comet has passed 2.69 AU from Saturn on 2013 Dec. 21 UT. See the previous orbits in NK 2046, NK 2090, NK 2261 and NK 2435 ( = HICQ 2013).
