Nakano Note (Nakano wa Kangaeru noda) NK 3003 P/LONEOS-Tucker (1998 QP54 = 2015 S1)
The following improved orbital elements, by S. Nakano, are from 246 observations 1998 to 2015. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.92 arc second. The residuals of the recovery observations from the prediction in NK 1047 (= HICQ 2015) were +2822" for R. A. and +1985" for Decl. with the delta-T correction = -1.86 days.
