Nakano Note (Nakano wa Kangaeru noda) NK 3038 P/Gibbs (2012 F5)
The following improved orbital elements, by S. Nakano, are from 124 observations 2004 to 2015. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.69 arc second. The residuals from the prediction in NK 2533 (= HICQ 2014) were -4" mainly for Right Ascension with the delta-T correction = +0.004 day. See the previous orbits in NK 2306 and NK 2533.
