Nakano Note (Nakano wa Kangaeru noda) NK 3030 P/2015 M2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 104 observations 2015 June 28 to Oct. 24. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.51 arc second. Epoch = 2015 Sept.15.0 TT T = 2015 Aug. 29.82378 +/- 0.54787 (m.e.) TT Peri. = 224.68293 +/- 0.04162 Node = 86.61816 +/- 0.00167 (2000.0) Inc. = 3.97425 +/- 0.00013 q = 5.9130242 +/- 0.0000841 AU e = 0.1788951 +/- 0.0000211 a = 7.2013017 +/- 0.0000294 AU n' = 0.05100204 +/- 0.00000031 P = 19.325 +/- 0.0001184 years (+/- 0.04 day) The predicted orbit for the 2035 return is as follows: T = 2035 Jan. 7.82680 TT Epoch = 2034 Dec. 24.0 TT Peri. = 223.44937 e = 0.1843436 Node = 86.21599 (2000.0) a = 7.2928397 AU Inc. = 3.96672 n'= 0.05004481 q = 5.9484517 AU P = 19.695 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2015/ 150711 474 0.4- 0.2- 150721 G45 0.2- 0.2- 150628 F51 0.2+ 0.0 150711 474 0.3- 0.1- 150721 G45 0.0 0.2- 150628 F51 0.0 0.0 150711 474 0.3- 0.0 150721 G45 0.8- 0.1- 150628 F51 0.3+ 0.2+ 150711 474 0.4- 0.0 150721 G45 0.8- 0.2- 150629 F51 0.2+ 0.1+ 150712 204 0.3+ 0.9- 150721 G45 0.7- 0.1- 150629 F51 0.4+ 0.1+ 150712 204 0.2- 0.4- 150725 F51 0.2+ 0.1+ 150630 F51 0.2+ 0.0 150712 291 0.2- 0.0 150725 F51 0.1+ 0.1+ 150630 F51 0.2- 0.0 150712 291 1.7- 0.4- 150725 F51 0.2+ 0.1+ 150630 F51 0.2+ 0.2+ 150712 291 1.2- 0.3- 150725 F51 0.0 0.0 150630 F51 0.1+ 0.2- 150712 G32 0.0 0.1- 150810 F51 0.2+ 0.0 150707 Q62 0.1- 0.0 150712 G32 1.0- 0.3- 150810 F51 0.0 0.5+ 150707 Q62 0.1- 0.1+ 150712 G32 0.9- 0.6- 150810 F51 0.2+ 0.1+ 150707 Q62 0.3- 0.1- 150712 G32 0.3- 0.2+ 150811 F51 0.0 0.1- 150708 291 1.2- 0.0 150712 E23 0.4- 0.5- 150811 F51 0.1+ 0.1+ 150708 291 1.5- 0.6- 150712 E23 0.2- 1.0- 150811 F51 0.1+ 0.1+ 150709 958 1.0- 0.8- 150712 E23 0.7- 0.7- 150812 215 1.4- 0.6+ 150709 958 0.1+ 0.4+ 150712 104 1.1- 0.5- 150812 215 1.5- 0.5+ 150709 W96 1.6- 0.3- 150712 104 0.8- 0.0 150812 215 0.6- 0.2- 150709 W96 1.2- 0.8- 150714 I93 0.4- 0.4- 150815 E07 0.4- 0.3- 150709 291 0.4- 0.6- 150714 I93 0.4- 0.4- 150815 E07 0.2- 0.5- 150709 291 0.4- 0.0 150714 G40 0.4- 0.7- 150822 474 0.4- 0.2- 150709 291 0.4- 0.2+ 150714 G40 1.0- 0.6- 150822 474 0.0 0.0 150709 958 1.1- 0.1+ 150714 G40 0.1- 0.2- 150822 474 0.1+ 0.1- 150710 958 1.4- 0.4- 150714 G40 0.1- 0.4- 150825 474 0.2- 0.6- 150710 958 1.3- 0.7- 150714 F51 0.3- 0.1+ 150825 474 0.4- 0.3- 150710 958 0.5- 0.6- 150714 F51 0.2+ 0.0 150825 474 0.3- 0.2- 150710 958 1.1- 0.0 150714 F51 0.0 0.0 150825 474 0.3- 0.4- 150710 958 0.5- 0.3- 150719 F51 0.3+ 0.2+ 150906 F51 0.1+ 0.0 150710 958 0.6- 0.7- 150719 F51 0.2+ 0.1+ 150906 F51 0.2- 0.1- 150710 958 0.8- 0.9- 150719 F52 0.3+ 0.0 150906 F51 0.1+ 0.1- 150710 W96 0.7- 0.1- 150719 F51 0.2+ 0.1+ 150906 F51 0.1- 0.2- 150710 W96 0.2- 0.0 150719 F52 0.1+ 0.1+ 151024 F51 0.2- 0.1+ 150711 291 1.9- 0.7- 150719 F51 0.1+ 0.1+ 151024 F51 0.3+ 0.1+ 150711 291 0.3- 0.1- 150719 F52 0.2+ 0.1+ 151024 F51 0.1- 0.1- 150711 291 0.3- 0.1- 150719 F52 0.1+ 0.0 151024 F51 0.1+ 0.0 ( ) -------- Rejected Obs.
