Nakano Note (Nakano wa Kangaeru noda) NK 3174 226P/Pigott-LINEAR-Kowalski
The following improved orbital elements, by S. Nakano, are from 220 observations 1995 to 2016, including planetary perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas, Vesta, and non-gravitational effect of style II. The mean residual is +/- 0.85 arc second. The re-observations in 2016 from the prediction in NK 2524 (= HICQ 2015) were +16" up for Right Ascension and +28" for Declination with the delta-T correction = -0.03 day. See the previous orbits in NK 919, NK 1826, NK 1827, NK 1854, NK 2524 and NK 2524R. Epoch = 2016 Sept. 9.0 TT T = 2016 Sept. 5.14158 +/- 0.00106 (m.e.)
