Nakano Note (Nakano wa Kangaeru noda) NK 3370 C/2016 T1 (Matheny)
The following improved orbital elements, S. Nakano, are from 129 observations 2016 Oct. 6 to 2017 May 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. The comet will pass 2.65 AU from Jupiter on 2017 Oct. 6 UT. The residuals for 2017 May observations were about +480" for Right Ascension and +315" for Declination from an orbit in HICQ 2017.
