Nakano Note (Nakano wa Kangaeru noda) NK 2424 C/2012 LP26 (Palomar)
The following improved orbital elements, by S. Nakano, are from 28 observations 2012 May 23 to 2013 Feb. 23. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.46 arc second. Epoch = 2015 Aug. 6.0 TT T = 2015 Aug. 16.60995 +/- 0.13306 (m.e.)
