Nakano Note (Nakano wa Kangaeru noda) NK 4782 C/2014 W5 (Lemmon-PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 69 observations 2014 Oct. 4 to 2016 May 5. 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 comet has passed 3.84 AU from Jupiter on 2013 Sept. 19 and 1.95 AU from Jupiter on 2017 Oct. 22, again. Outside observations from former orbit were reported, recently. So that orbit is great improved. See the previous orbit in NK 4049. Epoch = 2016 Feb. 22.0 TT T = 2016 Feb. 10.56336 +/- 0.00064 (m.e.)
