Nakano Note (Nakano wa Kangaeru noda) NK 3353 C/2016 E1 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 55 observations 2016 Mar. 3 to 2017 Mar. 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.29 arc second. The comet has passed 0.62 AU from Saturn on 2014 Nov. 14 UT. Residuals for 2017 March observations were -36" for Right Ascension and +29" for Declination from an orbit in HICQ 2017.
