The following improved orbital elements, by S. Nakano, are from 86 observations 2003 Sept. 27 to Dec. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.71 arc second. Epoch = 2003 July 20.0 TT T = 2003 July 2.08665 +/- 0.00290 (m.e.) TT Peri. = 119.37842 +/- 0.00109 Node = 245.75218 +/- 0.00012 (2000.0) Inc. = 16.33014 +/- 0.00056 q = 1.8315615 +/- 0.0000405 AU e = 0.5088733 +/- 0.0000232 a = 3.7293056 +/- 0.0000522 AU n' = 0.13685545 +/- 0.00000288 P = 7.202 +/- 0.0001513 years (+/- 0.06 day) The predicted orbit for the 2010 return is as follows: T = 2010 Sept. 9.57314 TT Epoch = 2010 Sept. 1.0 TT Peri. = 119.33307 e = 0.5092303 Node = 245.67030 (2000.0) a = 3.7312963 AU Inc. = 16.33161 n'= 0.13674595 q = 1.8312073 AU P = 7.208 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2003/ 031123 704 0.1- 0.4- 031216 703 1.5- 0.7- 030927 704 0.3+ 0.3- 031123 704 0.1+ 0.7- 031216 372 1.1+ 1.1+ 030927 704 0.7- 0.5- 031123 704 0.2+ 1.0- 031216 372 1.1+ 1.2+ 030927 704 (4.8- 1.2-) 031130 696 0.1+ 0.1- 031217 699 (2.1- 0.3+) 031005 704 1.1- 0.5- 031130 291 1.1- 0.2+ 031217 699 0.8- 0.7+ 031005 704 0.5+ 0.4- 031130 696 0.3+ 0.1- 031217 699 0.3+ 0.6+ 031005 704 1.2+ 0.6+ 031130 291 0.7- 0.0 031217 699 0.0 0.6+ 031029 704 1.7+ 1.8+ 031130 291 1.4+ 0.3- 031218 246 0.2- 0.2+ 031029 704 (2.2+ 1.3+) 031130 691 0.3+ 0.0 031218 246 0.7- 0.2+ 031029 704 0.4+ 0.2+ 031130 691 0.4+ 0.3- 031218 246 0.4- 0.1- 031029 704 0.3- 1.8+ 031130 691 0.2+ 0.0 031218 246 0.5+ 0.3- 031029 704 0.3+ 0.3- 031201 704 (2.0+ 0.2+) 031218 246 0.3+ 0.4- 031102 704 0.6+ 0.5- 031201 704 0.8+ 0.4+ 031218 246 0.1+ 0.6+ 031102 704 0.4- 1.4- 031201 704 1.0+ 1.2+ 031219 704 1.6- 0.1- 031102 704 0.3- 0.1- 031206 204 0.4+ 0.0 031219 704 1.0+ 0.4- 031102 704 1.3- 0.4+ 031206 204 0.5- 0.3+ 031219 704 1.1- 0.3- 031118 644 1.2+ 0.3- 031206 204 1.4+ 0.5- 031219 704 0.0 0.4+ 031118 644 0.1- 0.2- 031211 620 0.5- 0.0 031219 704 1.7+ 1.4- 031118 644 0.7- 0.0 031211 620 0.3- 0.2- 031220 104 0.8- 0.2- 031121 704 0.3- 0.2+ 031212 620 0.1+ 0.2- 031220 104 0.2+ 1.4- 031121 704 1.2- 0.2+ 031212 620 0.4+ 0.7- 031220 104 0.1- 0.2+ 031121 704 0.3- 0.1- 031212 213 0.3- 1.8- 031220 104 0.7- 0.9+ 031121 704 0.6- 0.2+ 031212 213 0.3+ 0.9- 031220 104 0.1- 1.0- 031121 704 0.9- 0.3+ 031212 213 0.3+ 0.5- 031221 704 1.0+ 1.2- 031123 704 1.5+ 0.0 031214 691 0.3- 0.3- 031221 704 0.3+ 1.2+ 031123 704 0.0 0.1+ 031214 691 0.2- 0.0 031221 704 0.5- 0.4+ 031123 704 0.2+ 0.2+ 031214 691 0.5- 0.4- 031221 704 0.4+ 0.6+ 031123 704 0.8- 0.0 031214 372 0.6+ 0.4+ 031228 360 0.7- 0.6- 031123 704 0.4- 0.4+ 031216 703 0.0 1.3+ 031228 360 0.8+ 0.8+ 031123 704 1.5- 0.2+ 031216 703 0.0 1.4+ 031228 360 0.1- 0.1+ 031123 704 0.3- 0.2- 031216 703 (4.8- 0.7+) ( ) -------- Rejected Obs.
