Nakano Note (Nakano wa Kangaeru noda) NK 3226 P/LINEAR (2008 SH164 = 2016 Q3)
The following improved orbital elements, by S. Nakano, are from 53 observations 2008 to 2016. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. The residuals of recovery observations were -234" for Right Ascension and -89" for Declination from the prediction in MPO 149062 with the delta-T correction = +0.26 day.
