Nakano Note (Nakano wa Kangaeru noda) NK 3036 P/2010 V1 (Ikeya-Murakami) = P10qxlX in PCCP

Hidetaka Sato, Tokyo, has identified an object P10qxlX in PCCP with P/2010 V1 (Ikeya-Murakami). The residuals from the prediction in NK 2490 (= HICQ 2015) were -6.81 deg for Right Ascension and +3.26 deg for Declination with the delta-T correction = +6.89 days. The comet was six magnitudes fainter than the predicted value. Also Sato estimates an object MaWi031 in PCCP is a fragment from this comet. The following improved orbital elements, by S. Nakano, are from 433 observations 2010 to 2016. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.65 arc second. See the previous orbits in NK 2025 and NK 2490. Epoch = 2016 Feb. 22.0 TT T = 2016 Mar. 17.30712 +/- 0.00170 (m.e.)
