Nakano Note (Nakano wa Kangaeru noda) NK 2799 P/2014 M4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 69 observations 2014 June 30 to Oct. 30. 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. Epoch = 2014 Dec. 9.0 TT T = 2014 Dec. 27.65201 +/- 0.01962 (m.e.) TT Peri. = 145.30482 +/- 0.00922 Node = 265.05388 +/- 0.00161 (2000.0) Inc. = 3.34527 +/- 0.00002 q = 2.3511370 +/- 0.0000977 AU e = 0.5955013 +/- 0.0000202 a = 5.8124703 +/- 0.0000649 AU n' = 0.07033362 +/- 0.00000118 P = 14.013 +/- 0.0002348 years (+/- 0.09 day) The predicted orbit for the 2029 return is as follows: T = 2029 Mar. 19.67003 TT Epoch = 2029 Mar. 5.0 TT Peri. = 148.16560 e = 0.5951947 Node = 263.10312 (2000.0) a = 5.8621776 AU Inc. = 3.34639 n'= 0.06944094 q = 2.3730405 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/ 140915 215 (2.5- 0.1-) 141001 F51 0.5+ 0.2- 140630 F51 0.1- 0.3+ 140915 215(67.7- 24.0-) 141003 691 0.7- 0.0 140630 F51 0.1- 0.1+ 140917 Q62 0.5- 0.3+ 141003 691 1.8- 0.3+ 140630 F51 0.2- 0.0 140917 Q62 0.5- 0.1- 141003 691 1.2- 1.7+ 140630 F51 0.1- 0.2- 140922 D95 0.4- 0.2- 141003 A77 1.0- 0.1- 140701 568 0.1- 0.0 140922 D95 0.6- 0.2+ 141003 A77 0.1- 0.3+ 140701 568 0.1- 0.0 140926 K25 0.3- 0.0 141015 691 0.6- 0.7+ 140702 W96 1.0+ 0.7+ 140926 K25 0.4+ 0.6- 141015 691 1.3- 0.2- 140702 W96 0.1- 0.5- 140927 A77 0.7- 0.0 141015 691 (2.6- 0.8-) 140702 W96 0.0 0.3- 140928 A77 1.1- 0.2+ 141017 A77 0.0 0.2- 140702 W96 0.3+ 1.8- 140928 A77 0.2- 0.3- 141017 K25 0.3+ 0.5- 140702 W96 (0.6+ 2.0-) 140928 A77 1.9- 1.1- 141017 A77 0.5+ 0.1+ 140702 568 0.2+ 0.1- 140928 A77 0.6- 0.3- 141017 K25 0.1+ 0.5- 140702 568 0.1+ 0.2- 140928 A77 1.0- 0.3+ 141018 372 0.6- 0.5+ 140702 568 0.2+ 0.1- 140928 D95 0.6+ 0.3- 141018 372 1.0- 0.1- 140702 Q62 0.2- 1.2+ 140928 D95 1.0- 0.9+ 141018 372 0.7- 0.1- 140702 Q62 0.5- 0.6+ 140928 349 1.9- 0.4+ 141018 215 (2.1- 0.7-) 140702 Q62 1.0- 0.2+ 140928 349 0.6- 0.7- 141018 215 0.2+ 1.0- 140708 809 1.6+ 1.2+ 140928 A77 0.8- 0.8- 141018 215 1.6+ 0.7- 140708 809 1.5+ 1.1+ 140929 A77 0.4- 0.8- 141022 G96 0.4- 0.2- 140708 809 (2.5+ 0.8+) 140929 W96 0.1+ 0.5+ 141022 G96 0.4- 0.0 140802 Q62 0.3- 0.2- 140929 W96 0.0 0.3+ 141022 G96 0.2- 0.0 140802 Q62 0.4- 0.2+ 140929 W96 0.3- 0.5- 141025 D95 0.4+ 1.0+ 140802 Q62 0.2- 0.1- 141001 F51 0.5+ 0.1+ 141025 D95 1.0- 0.2- 140915 215(68.3- 21.7-) 141001 F51 0.3+ 0.0 141029 A77 0.8+ 0.3+ 140915 215(67.9- 24.1-) 141001 F51 0.6+ 0.1+ 141030 A77 0.2- 0.3+ ( ) -------- Rejected Obs.
