The following improved orbital elements, by S. Nakano, are from 117 observations 2011 Feb. 10 to 2013 Oct. 30. 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 = 2011 Nov. 15.0 TT T = 2011 Nov. 29.93385 +/- 0.00397 (m.e.) TT Peri. = 173.50699 +/- 0.00115 Node = 58.74075 +/- 0.00059 (2000.0) Inc. = 8.45961 +/- 0.00004 q = 2.5283276 +/- 0.0000087 AU e = 0.2800154 +/- 0.0000095 a = 3.5116414 +/- 0.0000136 AU n' = 0.14977483 +/- 0.00000087 P = 6.581 +/- 0.0000382 years The predicted orbit for the 2018 return is as follows: T = 2018 June 22.57050 TT Epoch = 2018 June 11.0 TT Peri. = 173.11868 e = 0.2815092 Node = 58.72115 (2000.0) a = 3.5096822 AU Inc. = 8.46477 n'= 0.14990026 q = 2.5216745 AU P = 6.575 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2011/ 110225 703 1.2- 0.6+ 110325 703 1.1+ 0.4- 110210 703 0.2- 0.3- 110225 703 1.4- 0.3+ 110331 G96 0.2+ 0.0 110210 703 0.3- 0.2- 110228 J75 0.3- 0.0 110331 G96 0.9+ 0.0 110210 703 0.4- 0.2- 110228 J75 0.4- 0.2+ 110331 G96 0.2+ 0.1+ 110210 703 0.4- 0.3- 110228 J75 0.2- 0.2- 110331 G96 0.1- 0.2+ 110211 106 0.1- 0.4- 110303 H06 0.8+ 0.5+ 110506 B03 0.9+ 0.9+ 110211 106 0.0 0.2- 110303 H06 0.6+ 1.2+ 110506 B03 0.2- 0.6+ 110211 106 0.5+ 0.0 110303 H06 0.7+ 0.3+ 110506 B03 0.6+ 0.2+ 110211 106 0.0 0.3- 110303 H06 1.0+ 0.6+ 110506 B03 0.1+ 0.7+ 110211 H06 0.3+ 0.6- 110303 H06 0.9+ 0.6- 110507 B03 0.7+ 1.0+ 110211 H06 0.4+ 0.5- 110305 703 (2.2- 0.5+) 110507 B03 0.5+ 1.0+ 110211 H06 0.1+ 0.0 110305 703 0.7- 0.2+ 110507 B03 0.9+ 0.6+ 110211 H10 0.0 0.7- 110305 703 0.8- 0.6+ 110507 B03 (2.1+ 0.1-) 110211 H01 0.1+ 0.3- 110305 703 1.0- 0.3- 110624 H06 0.3- 0.1- 110211 H01 0.0 0.2- 110306 I41 0.1- 0.1+ 110624 H06 0.1+ 0.3+ 110211 850 0.1- 0.6- 110306 I41 0.1- 0.0 2013/ 110211 H10 0.0 0.6- 110306 I41 0.1- 0.1+ 130809 J43 0.2+ 0.0 110211 H01 0.0 0.3- 110306 I41 0.1- 0.1+ 130809 J43 0.8+ 0.1- 110211 H10 0.2- 0.2- 110308 704 (2.0+ 0.8+) 130809 J43 0.8+ 0.2+ 110211 H01 0.0 0.3- 110308 704 0.0 0.7+ 130810 J43 0.4+ 0.1- 110211 H10 0.2- 0.3+ 110308 704 1.2+ 0.3+ 130810 J43 0.3+ 0.0 110211 H10 0.5+ 0.7- 110308 704 0.4+ 0.5+ 130810 J43 0.0 0.2- 110211 H10 0.7+ 0.0 110310 G96 0.0 0.2+ 130810 J43 0.4+ 0.1- 110211 850 0.4+ 0.6- 110310 G96 0.0 0.0 130925 675 1.6- 0.0 110211 H06 0.8- 0.1+ 110310 G96 0.0 0.1- 130925 675 0.8- 0.2+ 110211 H06 0.1+ 0.3- 110310 G96 0.3+ 0.1+ 131001 Q62 0.2+ 0.3+ 110211 H06 0.9- 0.1- 110310 D29 0.8- 0.3- 131001 Q62 0.1+ 0.5+ 110211 H06 0.0 0.9- 110310 D29 0.3- 0.1- 131001 Q62 0.0 0.5+ 110211 H10 0.1- 0.1- 110310 D29 0.6+ 0.3+ 131002 H06 0.8+ 0.3- 110211 H10 0.0 0.0 110310 D29 0.8- 0.5+ 131002 H06 0.8+ 1.7- 110211 H10 0.2- 0.1- 110314 703 0.4+ 0.3- 131009 Q62 0.2- 0.9- 110211 H06 0.1+ 0.3+ 110314 703 0.1- 0.4- 131009 Q62 0.4+ 0.7- 110212 704 1.1+ 0.0 110314 703 0.5- 0.2+ 131024 Q62 1.3- 1.6+ 110212 704 0.6+ 0.9+ 110314 703 1.0- 0.5- 131024 Q62 0.6- 1.4+ 110212 704 0.1- 0.5+ 110325 703 0.3+ 0.4+ 131024 Q62 0.6- 0.9+ 110212 704 0.5+ 0.9+ 110325 703 0.2+ 0.1- 131025 Q62 1.0- 0.8+ 110212 704 0.0 1.0+ 110325 703 0.3- 0.1+ 131025 Q62 0.4- 0.8+ 110224 235 0.7- 0.1- 110325 703 0.1+ 0.2+ 131025 Q62 0.6- 1.1+ 110224 235 0.6- 0.3+ 110325 703 0.9+ 1.3- 131030 E10 0.4+ 0.0 110225 703 1.3- 0.5+ 110325 703 0.7+ 0.2- 131030 E10 0.6- 0.0 110225 703 1.5- 0.5+ 110325 703 0.2+ 0.8- ( ) -------- Rejected Obs.
