Nakano Note (Nakano wa Kangaeru noda) NK 5291 345P/LINEAR
The following improved orbital elements, by S. Nakano, are from 150 observations 2008 to 2024. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.71 arc second. 2024 September observations show the residuals of -28" for Right Ascension and -10" for Declination from the prediction in NK 4748 (= CH 2023) with the delta-T correction = +0.029 day. See the previous orbit in NK 3226 (= HICQ 2017) and NK 4748. Epoch = 2024 Sept. 7.0 TT T = 2024 Aug. 30.55704 +/- 0.00939 (m.e.)
