Nakano Note (Nakano wa Kangaeru noda) NK 2090 C/2010 L3 (Catalina)
The following improved orbital elements, by S. Nakano, are from 97 observations 2010 June 15 to 2011 May 4. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.54 arc second. The comet will pass 2.69 AU from Saturn on 2013 Dec. 21 UT. See the previous orbits on HICQ 2010/2011 and NK 2046. Epoch = 2010 Nov. 20.0 TT T = 2010 Nov. 10.29798 +/- 0.15367 (m.e.)
