Nakano Note (Nakano wa Kangaeru noda) NK 2800 P/2014 MG4 (Spacewatch-PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 88 observations 2014 June 20 to Oct. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.56 arc second. Epoch = 2013 May 28.0 TT T = 2013 June 13.68426 +/- 0.05397 (m.e.) TT Peri. = 298.89466 +/- 0.01028 Node = 311.86148 +/- 0.00009 (2000.0) Inc. = 9.36686 +/- 0.00045 q = 3.7150512 +/- 0.0001913 AU e = 0.2586184 +/- 0.0000635 a = 5.0109842 +/- 0.0000999 AU n' = 0.08786573 +/- 0.00000263 P = 11.217 +/- 0.0003355 years (+/- 0.12 day) The predicted orbit for the 2024 return is as follows: T = 2024 Sept. 5.95893 TT Epoch = 2024 Sept. 7.0 TT Peri. = 298.97170 e = 0.2584811 Node = 311.69302 (2000.0) a = 5.0133513 AU Inc. = 9.36439 n'= 0.08780351 q = 3.7174946 AU P = 11.225 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 140726 958 0.6- 0.1- 140803 F51 0.4+ 0.4- 140620 691 0.4+ 0.1+ 140726 958 0.7- 0.1+ 140804 K25 0.6- 0.6+ 140620 691 0.1+ 0.4+ 140727 958 0.7- 0.4+ 140804 K25 0.9- 0.9+ 140620 691 0.3+ 0.7+ 140727 W96 1.7- 0.4- 140805 F51 0.0 0.0 140620 691 0.1+ 0.7+ 140727 W96 0.5- 0.3+ 140805 F51 0.0 0.1+ 140620 691 0.2+ 0.6+ 140727 H06 0.6- 1.1+ 140805 F51 0.0 0.1+ 140620 691 0.0 0.7+ 140727 H06 0.8- 0.7+ 140816 474 0.1- 0.2+ 140621 691 0.5- 0.7+ 140727 Q62 1.7- 0.1+ 140816 474 0.1- 0.3+ 140621 691 0.0 0.7+ 140727 Q62 0.1- 1.0+ 140816 474 0.0 0.2+ 140621 691 0.7+ 0.2+ 140727 Q62 0.1- 0.6+ 140818 585 0.3- 0.2+ 140621 691 0.5- 0.8+ 140727 Q62 0.1+ 0.3- 140818 585 0.3- 0.2+ 140621 691 0.8- 0.5+ 140727 104 0.4- 0.4+ 140818 585 0.3- 0.6+ 140621 691 0.2- 0.5+ 140727 104 0.3- 0.4+ 140818 585 0.1- 0.1+ 140725 F51 0.3+ 0.1- 140727 104 0.3- 0.4+ 140818 585 0.7- 0.7+ 140725 F51 0.3+ 0.2- 140728 W96 0.8- 0.4+ 140818 585 0.5- 1.1+ 140726 G45 0.5- 0.7+ 140728 W96 0.7- 0.1+ 140818 585 0.4- 1.4+ 140726 G45 1.2- 1.1+ 140728 J01 0.4- 0.9+ 140827 F51 0.1+ 0.1- 140726 G45 1.2- 0.5+ 140728 J01 0.5- 0.3+ 140827 F51 0.1+ 0.1- 140726 G45 1.2- 0.3+ 140729 J01 0.5- 0.2+ 140827 F51 0.1+ 0.2- 140726 G45 0.5- 0.7+ 140730 F51 0.1+ 0.2- 140827 F51 0.1+ 0.2- 140726 G45 0.4- 0.7+ 140730 F51 0.1+ 0.2- 140914 E07 0.1- 1.0+ 140726 568 0.1+ 0.5- 140730 F51 0.1+ 0.2- 140914 E07 0.3+ 0.7+ 140726 568 0.3+ 0.5- 140730 F51 0.1+ 0.3- 140915 215 (2.9- 1.2-) 140726 568 0.4+ 0.3- 140730 C77 1.0- 0.6+ 140915 215 (2.7- 1.4-) 140726 300 0.5- 1.3+ 140730 C77 0.5- 0.4+ 140915 215 (2.5- 1.4-) 140726 300 0.2- 0.6+ 140730 C77 0.1- 0.3+ 140928 A77 0.8- 0.9+ 140726 300 0.3- 1.0+ 140731 K25 0.5- 0.6+ 140928 A77 0.1- 0.9+ 140726 300 0.0 1.3+ 140731 K25 1.1- 0.8+ 141018 215 0.0 1.0+ 140726 194 0.0 0.1+ 140803 F51 0.0 0.1- 141018 215 0.1- 0.9+ 140726 194 0.2- 0.2+ 140803 F51 0.0 0.1- 141018 215 0.0 0.5+ 140726 194 0.0 0.1+ 140803 F51 0.0 0.1- ( ) -------- Rejected Obs.
