The following improved orbital elements, by S. Nakano, are from 140 observations 2004 Sept. 10 to Nov. 16. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.60 arc second. Epoch = 2004 June 4.0 TT T = 2004 May 24.48313 +/- 0.02001 (m.e.) TT Peri. = 5.29025 +/- 0.00991 Node = 318.80963 +/- 0.00201 (2000.0) Inc. = 7.97291 +/- 0.00037 q = 2.1414936 +/- 0.0000612 AU e = 0.4418599 +/- 0.0000638 a = 3.8368391 +/- 0.0001179 AU n' = 0.13114257 +/- 0.00000604 P = 7.516 +/- 0.0003463 years (+/- 0.13 day) The predicted orbit for the 2011 return is as follows: T = 2011 Nov. 28.70587 TT Epoch = 2011 Nov. 15.0 TT Peri. = 5.54921 e = 0.4428010 Node = 318.72732 (2000.0) a = 3.8270262 AU Inc. = 7.97459 n'= 0.13164729 q = 2.1324151 AU P = 7.487 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2004/ 040917 A46 0.7- 0.8- 041004 A13 0.2- 0.3- 040910 704 0.7- 0.0 040917 A46 0.2- 0.6- 041004 A13 0.4- 0.7+ 040910 704 0.9+ 1.0+ 040917 J87 0.4+ 0.2- 041005 D74 0.4+ 0.7+ 040910 704 0.8+ 1.2+ 040917 J87 1.4- 1.6- 041005 D74 0.5+ 1.0- 040910 704 0.8+ 0.8+ 040917 246 0.6- 0.2+ 041005 D74 0.2+ 0.2- 040913 644 0.5- 0.2+ 040917 246 0.3- 0.1+ 041006 360 0.0 0.8+ 040913 704 0.4+ 1.3+ 040917 246 0.2+ 0.5+ 041006 360 0.3+ 0.3+ 040913 704 0.2+ 0.2+ 040917 246 0.1- 0.3+ 041006 360 0.1- 0.4+ 040913 644 0.2+ 0.4+ 040917 246 0.3+ 0.1- 041009 699 0.6+ 0.7+ 040913 704 0.1+ 0.1- 040917 246 0.3- 0.5+ 041009 699 0.3- 0.3+ 040913 644 0.1- 0.2+ 040917 246 0.1- 0.3+ 041009 699 0.2- 0.7- 040915 699 0.3+ 1.4- 040918 170 0.6- 0.8- 041009 699 0.7+ 1.0- 040915 699 0.5- 0.3- 040918 170 0.4- 0.9- 041010 704 0.0 0.8+ 040915 699 1.0- 1.6- 040918 170 0.1- 0.9- 041010 704 0.8+ 1.5+ 040915 699 0.1- 0.8- 040918 204 0.2+ 0.6+ 041010 704 0.2+ 0.6+ 040915 J95 1.0- 0.3- 040918 204 0.1- 0.0 041010 704 0.3- 0.2- 040915 J95 0.9- 1.1- 040918 704 (2.8- 3.3-) 041010 704 0.1- 0.7+ 040915 J95 0.8+ 0.6- 040918 704 0.2+ 1.4- 041010 213 0.6+ 0.4- 040915 J95 0.9- 1.2- 040918 704 0.9- 1.2+ 041010 213 0.9+ 1.4- 040916 G90 0.0 0.6+ 040918 704 0.2- 0.0 041010 213 0.6+ 1.1- 040916 649 0.0 0.3- 040918 215 0.5+ 0.4+ 041011 170 0.1- 1.1- 040916 G90 0.2- 0.2+ 040919 118 0.6- 0.4- 041011 170 0.3- 0.8- 040916 G90 0.0 0.1+ 040919 118 0.3- 0.5- 041011 170 0.0 0.2- 040916 649 0.3- 0.5- 040919 D74 0.9+ 0.6+ 041012 360 0.1+ 0.6+ 040916 649 0.3+ 0.1- 040919 D74 0.1+ 0.5+ 041012 360 0.2- 0.1+ 040916 673 0.5+ 0.5+ 040919 D74 1.1- 0.2- 041012 360 0.1- 0.2+ 040916 673 0.5+ 0.3+ 040922 704 0.0 0.5- 041015 704 0.6+ 1.2- 040916 673 0.3+ 0.5+ 040922 704 0.0 0.3- 041015 704 0.0 0.5+ 040916 673 0.1+ 0.3+ 040922 704 0.8- 0.5- 041015 704 (2.1- 0.5+) 040916 673 0.2+ 0.5+ 040922 704 0.2- 1.1+ 041018 118 0.4+ 0.3- 040916 673 0.6+ 0.5+ 040922 213 0.6- 0.1+ 041018 118 0.1- 0.6- 040916 704 0.5+ 0.4- 040922 213 0.5- 0.1+ 041020 213 0.5- 0.6+ 040916 673 0.3+ 0.6+ 040922 213 0.8- 0.1+ 041020 213 0.9- 0.5+ 040916 854 0.1+ 0.2+ 040924 170 0.2- 0.3- 041021 360 0.1+ 0.3+ 040916 704 0.7+ 0.5- 040924 170 0.1- 0.5- 041021 360 0.3- 0.0 040916 704 0.8+ 0.4+ 040924 170 0.2- 0.5- 041105 213 0.5- 1.1- 040916 854 0.7- 0.2+ 040924 170 0.1- 0.6- 041105 213 0.2- 0.5- 040916 854 0.5+ 0.1+ 040925 213 0.0 0.0 041105 213 0.1- 0.4- 040916 704 1.3+ 0.2+ 040930 118 0.1- 0.4- 041106 360 0.6- 0.0 040916 704 1.5+ 0.3+ 041001 118 0.1+ 0.3- 041106 360 0.1- 0.3+ 040916 734 (2.4- 0.5-) 041001 673 0.2+ 0.9+ 041107 360 0.1- 0.1+ 040916 704 0.1- 0.3+ 041001 673 0.4+ 0.6+ 041107 360 0.2- 0.1+ 040916 734 1.7+ 0.1- 041001 673 0.4+ 0.5+ 041109 850 0.0 0.4- 040916 704 0.2- 1.9+ 041001 673 0.1+ 0.9+ 041109 850 (0.4- 3.1-) 040916 704 0.1+ 0.7+ 041003 213 0.2+ 1.4+ 041110 850 (0.8- 2.5+) 040917 A46 0.5- 1.3- 041003 213 0.0 0.8+ 041110 850 0.6+ 0.2+ 040917 A46 0.6- 0.3- 041003 213 0.4- 0.8+ 041116 204 0.2- 0.3+ 040917 A46 0.4- 1.1- 041004 A13 0.5- 0.0 041116 204 0.9+ 0.2+ 040917 A46 0.0 1.4- 041004 A13 0.1- 0.7+ ( ) -------- Rejected Obs.
