Nakano Note (Nakano wa Kangaeru noda) NK 2755 307P/LINEAR (2000 QJ46 = 2014 O1)
The following improved orbital elements, by S. Nakano, are from 53 observations 2000 to 2014. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. The recovery observations show the residual of +4300" (R. A.) and +1271" (Decl.) from the prediction in NK 1285 (= HICQ 2013) with the delta-T correction = -2.32 days. On the other hand, the delta-T correction was only -0.24 day from the prediction by B. G. Marsden (CBET 3923). Epoch = 2014 Dec. 9.0 TT T = 2014 Dec. 20.23565 +/- 0.00202 (m.e.)
