Nakano Note (Nakano wa Kangaeru noda) NK 2966 P/2014 M4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 81 observations 2014 June 30 to Nov. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.69 arc second. See the previous orbit in NK 2799. Epoch = 2014 Dec. 9.0 TT T = 2014 Dec. 27.64116 +/- 0.01871 (m.e.) TT Peri. = 145.29899 +/- 0.00871 Node = 265.05536 +/- 0.00149 (2000.0) Inc. = 3.34526 +/- 0.00002 q = 2.3511868 +/- 0.0000906 AU e = 0.5954861 +/- 0.0000209 a = 5.8123764 +/- 0.0000645 AU n' = 0.07033532 +/- 0.00000117 P = 14.013 +/- 0.0002333 years (+/- 0.09 day) The predicted orbit for the 2029 return is as follows: T = 2029 Mar. 19.49347 TT Epoch = 2029 Mar. 5.0 TT Peri. = 148.15835 e = 0.5951798 Node = 263.10571 (2000.0) a = 5.8620479 AU Inc. = 3.34637 n'= 0.06944325 q = 2.3730756 AU P = 14.193 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 140926 K25 0.5+ 0.6- 141017 A77 0.7+ 0.1+ 140630 F51 0.1- 0.3+ 140927 A77 0.6- 0.1- 141017 K25 0.2+ 0.5- 140630 F51 0.1- 0.2+ 140928 A77 1.0- 0.2+ 141018 372 0.5- 0.5+ 140630 F51 0.2- 0.0 140928 A77 0.1- 0.3- 141018 372 0.9- 0.2- 140630 F51 0.1- 0.1- 140928 A77 1.8- 1.1- 141018 372 0.6- 0.1- 140701 568 0.1- 0.0 140928 A77 0.5- 0.3- 141018 215 (2.0- 0.7-) 140701 568 0.1- 0.0 140928 A77 0.9- 0.2+ 141018 215 0.3+ 1.0- 140702 W96 1.0+ 0.8+ 140928 D95 0.6+ 0.4- 141018 215 1.7+ 0.7- 140702 W96 0.1- 0.5- 140928 D95 1.0- 0.8+ 141022 G96 0.3- 0.3- 140702 W96 0.0 0.2- 140928 349 1.9- 0.4+ 141022 G96 0.2- 0.0 140702 W96 0.3+ 1.8- 140928 349 0.5- 0.7- 141022 G96 0.1- 0.0 140702 W96 0.6+ 1.9- 140928 A77 0.8- 0.8- 141023 G45 1.8- 0.0 140702 568 0.1+ 0.0 140929 A77 0.4- 0.9- 141023 G45 0.3- 0.5+ 140702 568 0.1+ 0.1- 140929 W96 0.1+ 0.4+ 141023 G45 1.0- 0.5+ 140702 568 0.1+ 0.1- 140929 W96 0.1+ 0.3+ 141023 G45 0.6- 0.2+ 140702 Q62 0.2- 1.3+ 140929 W96 0.3- 0.5- 141024 G45 0.4- 0.4- 140702 Q62 0.5- 0.7+ 141001 F51 0.6+ 0.1+ 141024 G45 0.1- 0.1+ 140702 Q62 1.0- 0.2+ 141001 F51 0.3+ 0.0 141024 G45 0.7- 0.5+ 140708 809 1.5+ 1.2+ 141001 F51 0.7+ 0.1+ 141024 G45 (2.0- 1.2+) 140708 809 1.4+ 1.1+ 141001 F51 0.6+ 0.3- 141024 G45 1.9- 0.4+ 140708 809 (2.4+ 0.8+) 141003 691 0.6- 0.0 141025 D95 0.6+ 0.9+ 140802 Q62 0.5- 0.3- 141003 691 1.7- 0.3+ 141025 D95 0.9- 0.2- 140802 Q62 0.6- 0.1+ 141003 691 1.1- 1.6+ 141027 A71 0.5- 0.4- 140802 Q62 0.4- 0.2- 141003 A77 0.9- 0.1- 141027 A71 0.2+ 0.9+ 140915 215 (2.5- 0.2-) 141003 A77 0.0 0.2+ 141029 A77 0.9+ 0.2+ 140917 Q62 0.5- 0.2+ 141015 691 0.5- 0.7+ 141030 A77 0.0 0.2+ 140917 Q62 0.5- 0.2- 141015 691 1.1- 0.3- 141118 130 1.4+ 1.1+ 140922 D95 0.4- 0.3- 141015 691 (2.5- 0.8-) 141118 130 (2.2+ 1.4+) 140922 D95 0.6- 0.1+ 141017 A77 0.2+ 0.2- 140926 K25 0.3- 0.1- 141017 K25 0.5+ 0.6- ( ) -------- Rejected Obs.
