Nakano Note (Nakano wa Kangaeru noda) NK 4771 C/2014 G1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 85 observations 2013 Apr. 17 to 2014 Aug. 12. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.45 arc second. The comet has passed 7.45 AU from Uranus on 2008 July 8, 4.35 AU from Saturn on 2014 Sept. 9 and 3.45 AU from Jupiter on 2016 June 24 UT. See an orbit in HICQ 2015.
