Nakano Note (Nakano wa Kangaeru noda) NK 3074 C/2014 W3 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 47 observations 2014 Nov. 18 to 2016 Feb. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.49 arc second. The comet has passed 1.80 AU from Jupiter on 2014 June 11 UT. 2016 observations show the residuals of -308" for Right Ascension and -113" for Declination from an orbit in HICQ 2015. Epoch = 2014 Mar. 4.0 TT T = 2014 Feb. 25.26792 +/- 0.00863 (m.e.)
