Nakano Note (Nakano wa Kangaeru noda) NK 2061 P/2010 L5 (WISE)
The following improved orbital elements, by S. Nakano, are from 29 observations 2010 June 14 to July 15. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second. See an orbit on HICQ 2010/2011. Epoch = 2010 May 4.0 TT T = 2010 Apr. 23.05792 +/- 0.03926 (m.e.)
