Nakano Note (Nakano wa Kangaeru noda) NK 3431 11P/Tempel-Swift-LINEAR
The following improved orbital elements, by S. Nakano, are from 100 observations 1908 to 2015, including planetary perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas, Vesta, and non-gravitational effect of style II. The mean residual is +/- 0.81 arc second. The comet has passed 0.61 AU, 0.50 AU and 0.54 AU from Jupiter on 1911 May 26, 1923 July 7 and 1935 Apr. 23 UT, respectively, and will pass 0.60 AU and 0.52 AU from Jupiter on 2018 Sept. 14 and 2030 July 22 UT, respectively. See the previous orbits in NK 396, NK 686, MPC 44184 (= IAUC 7779), NK 1197, NK 2163 and NK 2776. Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 26.92511 +/- 0.00029 (m.e.)
