Nakano Note (Nakano wa Kangaeru noda) NK 3041 P/2015 P4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 74 observations 2015 July 24 to Dec. 11. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.38 arc second. Epoch = 2016 Jan. 13.0 TT T = 2016 Jan. 19.04509 +/- 0.00507 (m.e.) TT Peri. = 280.82403 +/- 0.00214 Node = 104.74438 +/- 0.00032 (2000.0) Inc. = 8.71364 +/- 0.00003 q = 2.5250813 +/- 0.0000219 AU e = 0.5841463 +/- 0.0000153 a = 6.0720418 +/- 0.0000379 AU n' = 0.06587217 +/- 0.00000062 P = 14.962 +/- 0.0001401 years (+/- 0.05 day) The predicted orbit for the 2030 return is as follows: T = 2030 Dec. 13.26906 TT Epoch = 2030 Dec. 5.0 TT Peri. = 280.62449 e = 0.5845038 Node = 104.60032 (2000.0) a = 6.0700437 AU Inc. = 8.71561 n'= 0.06590469 q = 2.5220799 AU P = 14.955 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2015/ 150819 Q62 0.0 0.9- 150918 372 0.3+ 0.7+ 150724 F51 0.0 0.1- 150821 F51 0.2+ 0.1- 150918 372 0.2+ 0.8- 150724 F51 0.0 0.2+ 150821 F51 0.0 0.0 150921 372 0.0 0.1+ 150724 F51 0.0 0.1+ 150821 F51 0.0 0.1- 150921 372 0.3- 0.4+ 150814 F51 0.0 0.2- 150821 F51 0.0 0.1- 150921 372 0.5- 0.8+ 150814 F51 0.0 0.1- 150826 215 0.4- 0.2- 151009 F51 0.1- 0.0 150814 F51 0.2+ 0.0 150826 215 0.1- 0.1- 151009 F51 0.2- 0.0 150814 F51 0.1+ 0.0 150826 215 0.2+ 0.2- 151009 F51 0.0 0.0 150816 H21 0.3- 0.0 150906 F51 0.0 0.0 151009 F51 0.1- 0.0 150816 H21 0.2- 0.3- 150906 F51 0.0 0.0 151109 474 0.0 0.3- 150816 H21 0.8- 0.0 150906 F51 0.3+ 0.2+ 151109 474 0.1+ 0.1- 150819 958 1.7- 0.7+ 150907 474 0.2- 0.1+ 151109 474 0.3+ 0.3- 150819 958 0.1+ 0.8- 150907 474 0.2- 0.2+ 151129 G45 0.7+ 1.2+ 150819 W96 0.6- 0.1- 150907 474 0.0 0.1+ 151129 G45 0.2+ 0.1- 150819 W96 0.2- 0.0 150907 474 0.2- 0.0 151129 G45 0.3+ 0.4- 150819 W96 0.7- 0.3- 150914 G45 0.1- 0.1+ 151129 G45 0.4- 0.4+ 150819 W96 0.0 0.5- 150914 G45 1.0+ 0.0 151202 G45 0.0 0.2+ 150819 H01 0.2- 0.2+ 150914 G45 0.6+ 0.0 151202 G45 0.1- 0.3+ 150819 H01 0.1- 0.3+ 150914 G45 1.4+ 0.4+ 151202 G45 0.9- 0.2- 150819 H01 0.3- 0.2- 150914 Q60 (2.5+ 0.6+) 151202 G45 1.2+ 0.4+ 150819 H01 0.3- 0.1+ 150914 Q60 0.9- 1.5+ 151202 G45 0.3- 0.0 150819 291 0.1- 0.1+ 150914 Q60 (2.6- 0.2+) 151211 474 0.0 0.7- 150819 291 0.0 0.4+ 150918 Q60 0.7+ 0.5+ 151211 474 0.2- 0.1- 150819 291 0.0 0.2+ 150918 Q60 0.3- 0.5- 151211 474 0.4+ 0.5- 150819 Q62 0.2- 0.1+ 150918 Q60 (2.0- 0.1+) 151211 474 0.3+ 0.4- 150819 Q62 0.1- 0.6- 150918 372 0.7- 0.2+ 151211 474 0.0 0.4- ( ) -------- Rejected Obs.
