Nakano Note (Nakano wa Kangaeru noda) NK 2693 P/LINEAR-NEAT (2001 BB50 = 2014 K1)
The following improved orbital elements, by S. Nakano, are from 104 observations 2001 to 2014. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.58 arc second. The residuals of recovery observations from the prediction in NK 828 (= HICQ 2014) were +1387" for R. A. and -667" for Decl. with the delta-T corection = -1.79 days.
