Nakano Note (Nakano wa Kangaeru noda) NK 3169 P/WISE (2010 N1 = 2016 GE216)
The following improved orbital elements, by S. Nakano, are from 114 observations 2010 to 2016. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second. The residuals for the recovery observation on Apr. 10 were +0.52 deg for Right Ascension and -0.21 deg for Declination from the prediction in NK 2494 (= HICQ 2015) with the delta-T correction = -0.66 day. Epoch = 2016 July 31.0 TT T = 2016 July 13.23051 +/- 0.00008 (m.e.)
