Nakano Note (Nakano wa Kangaeru noda) NK 2546 P/2012 Q1 (Kowalski)
The following improved orbital elements, by S. Nakano, are from 146 observations 2011 Apr. 13 to 2013 Aug. 1. 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 the previous orbits in NK 2377 and NK 2404 (= HICQ 2013). Epoch = 2012 Feb. 3.0 TT T = 2012 Feb. 9.11841 +/- 0.04765 (m.e.)
