Nakano Note (Nakano wa Kangaeru noda) NK 3323 P/2015 V4 (PANSTARRS)
The following improved orbital elements, by T. Kobayashi, are from 67 observations 2015 Nov. 3 to 2016 Nov. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second. The comet will pass 3.99 AU from Jupiter on 2017 July 17 UT. See the previous orbits in NK 3078, NK 3154 and HICQ 2016. Epoch = 2016 Sept. 9.0 TT T = 2016 Aug. 28.27737 +/- 0.01402 (m.e.) TT Peri. = 306.93615 +/- 0.00144 Node = 179.89560 +/- 0.00014 (2000.0) Inc. = 60.75168 +/- 0.00005 q = 5.4594747 +/- 0.0000104 AU e = 0.7056396 +/- 0.0000104 a = 18.5469076 +/- 0.0000000 AU n' = 0.01233948 +/- 0.00000066 P = 79.874 +/- 0.0042481 years (+/- 1.55 days) The predicted orbit for the 2095 return from an orbit in HICQ 2016 is as follows: T = 2095 Oct. 26.11824 TT Epoch = 2095 Nov. 14.0 TT Peri. = 306.70460 e = 0.7079506 Node = 179.80268 (2000.0) a = 18.6966830 AU Inc. = 60.71779 n'= 0.01219150 q = 5.4603542 AU P = 80.844 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2015/ 151108 W96 0.1- 0.4- 160202 474 0.3- 0.2+ 151103 F51 0.7+ 0.2+ 151113 W96 0.0 0.0 160202 474 0.4- 0.1+ 151103 F51 0.0 0.0 151113 W96 0.3- 0.0 160202 474 0.2- 0.1+ 151103 F51 0.2+ 0.1+ 151113 W96 0.4+ 0.8- 160202 474 0.2- 0.2+ 151105 K91 0.1+ 0.1- 151204 Q62 0.5+ 0.1- 160209 E07 0.3- 0.0 151105 K91 0.5+ 0.0 151204 Q62 0.0 0.0 160209 E07 0.4- 0.2+ 151105 K91 0.2+ 0.0 151204 Q62 0.5- 0.3+ 160210 E07 0.0 0.4+ 151105 W85 0.3+ 0.1- 151210 474 0.5+ 0.4+ 160210 E07 0.3- 0.5+ 151105 W85 0.5+ 0.0 151210 474 0.0 0.1- 160308 474 0.5- 0.6+ 151105 W85 0.1+ 0.2- 151210 474 0.4- 0.0 160308 474 0.1+ 0.7+ 151105 W85 0.2+ 0.3- 151215 W96 0.3+ 1.1+ 160308 474 0.8- 0.4+ 151105 807 0.0 0.1- 151215 W96 0.1- 0.3- 160308 474 0.3+ 0.1- 151105 807 0.2+ 0.3+ 151215 W96 0.1- 0.2- 160413 474 0.4+ 0.0 151105 807 0.3+ 0.7- 151231 Q62 0.2- 0.8- 160413 474 0.0 0.1- 151106 568 0.1+ 0.2+ 151231 Q62 0.6- 0.1- 160413 474 0.0 0.3- 151106 568 0.0 0.2+ 151231 Q62 0.2- 0.5- 160413 474 0.2+ 0.3+ 151106 568 0.1+ 0.1+ 2016/ 160503 474 1.0+ 0.6- 151107 Q62 0.8- 0.4+ 160104 474 0.1- 0.2+ 160503 474 0.5+ 0.6- 151107 Q62 0.5- 0.0 160104 474 0.1+ 0.2+ 160503 474 0.1- 1.3- 151107 Q62 0.5- 0.3- 160104 474 0.0 0.1- 160503 474 0.2+ 0.4- 151108 W96 0.2+ 0.2- 160104 474 0.1- 0.0 161103 Q62 0.1- 0.2+ 151108 W96 0.2- 0.3+ 160112 E07 0.2- 0.0 161103 Q62 0.0 0.2+ 151108 W96 0.7+ 0.4+ 160112 E07 0.1- 0.0 161103 Q62 0.2+ 0.1+ ( ) -------- Rejected Obs.
