Nakano Note (Nakano wa Kangaeru noda) NK 2999 C/2014 L5 (Lemmon)

The following improved orbital elements, S. Nakano, are from 67 observations 2013 Oct. 12 to 2015 July 22. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.43 arc second. 2015 July observations show the residuals of +3" for mainly R. A. from an orbit in NK 2798 (= HICQ 2015).
