Nakano Note (Nakano wa Kangaeru noda) NK 2965 C/2014 M1 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 45 observations 2014 June 24 to 2015 July 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. The residuals of 2015 June observations were -35" for R. A. and +8" for Decl. from a latest orbit. The comet will pass 4.44 AU from Saturn on 2015 Dec. 26 and 1.96 AU from Jupiter on 2017 Apr. 24 UT.
