Nakano Note (Nakano wa Kangaeru noda) NK 5635 P/Schwartz (2013 T2 = P22oEGl)
The following improved orbital elements, by S. Nakano, are from 124 observations 2013 to 2026. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. Residuals for the recovery observations in 2026 were +11'.0 for Right Ascension and +7'.1 for Declination from the prediction in NK 3212 (= HICQ 2026) with the delta-T correction = -0.54 day. The comet has passed 0.99 AU from Jupiter on 2015 Oct. 6 and 0.27 AU from Jupiter on 2004 June 7 UT. See the previous orbit in NK 3212.
