Nakano Note (Nakano wa Kangaeru noda) NK 4772 C/2014 M2 (Christensen)
The following improved orbital elements, by S. Nakano, are from 55 observations 2013 May 6 to 2014 Sept. 29. 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 4.81 AU from Saturn on 2012 Apr. 1 and will pass 7.04 AU from Uranus on 2023 July 16 UT. See the previous orbit in NK 2904. Note Observations on 2015 September are a different object. Epoch = 2014 July 2.0 TT T = 2014 July 12.66896 +/- 0.08304 (m.e.)
