The following improved orbital elements, by S. Nakano, are from 54 observations 2000 Sept. 3 to Nov. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.64 arc second. Epoch = 2000 Sept.13.0 TT T = 2000 Sept.12.65740 +/- 0.00228 (m.e.) TT Peri. = 147.06327 +/- 0.00194 Node = 187.49916 +/- 0.00131 (2000.0) Inc. = 3.21639 +/- 0.00023 q = 1.3899763 +/- 0.0000393 AU e = 0.5836796 +/- 0.0001118 a = 3.3387178 +/- 0.0002701 AU n' = 0.16156025 +/- 0.00001960 P = 6.101 +/- 0.0007403 years (+/- 0.27 day) The predicted orbit for the 2006 return is as follows: T = 2006 Dec. 15.05006 TT Epoch = 2006 Dec. 11.0 TT Peri. = 172.23392 e = 0.5650841 Node = 163.09937 (2000.0) a = 3.3482824 AU Inc. = 10.99295 n'= 0.16086848 q = 1.4562213 AU P = 6.127 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2000/ 000906 344 0.0 0.6+ 000918 704 0.0 0.1- 000903 704 0.3- 1.9- 000906 344 0.4+ 0.7+ 000918 853 0.3- 0.1- 000903 704 0.6- 0.1+ 000906 344 0.1+ 0.2- 000918 853 0.1+ 0.4- 000903 704 1.4+ 0.8- 000907 658 1.1+ 1.4+ 000920 360 0.3+ 0.0 000903 704 0.2+ 0.7- 000907 658 0.5- 0.0 000920 360 0.2- 0.1+ 000904 704 1.1- 0.5+ 000907 658 1.8- 0.1- 000920 360 0.2+ 0.6- 000904 704 0.9- 0.1+ 000907 046 1.0+ 0.6- 000924 704 0.6- 1.0+ 000904 704 0.1- 0.5- 000907 046 0.1+ 0.5+ 000924 704 0.8- 0.0 000904 704 (2.1+ 0.4+) 000911 658 0.7+ 0.5+ 000924 704 0.2- 0.5+ 000905 704 0.4- 0.2- 000911 658 0.5- 0.1+ 000924 704 0.9+ 0.5- 000905 704 0.5+ 0.4+ 000911 658 0.7- 0.8+ 000927 360 0.7+ 1.1- 000905 704 0.3- 0.7+ 000916 853 0.8- 0.3- 000927 360 0.5- 0.7- 000905 704 1.1- 0.8- 000916 853 0.9- 0.3- 000927 360 0.7+ 0.2- 000906 808 1.8+ 1.9+ 000916 853 0.2- 0.3- 001122 360 0.4- 0.3- 000906 808 (1.0+ 2.3+) 000918 734 0.2+ 0.3+ 001122 360 0.5+ 0.2- 000906 704 0.1+ 0.8- 000918 734 0.2+ 0.4+ 001122 360 0.1+ 0.5+ 000906 704 0.3+ 0.4+ 000918 704 0.6+ 0.3+ 001129 360 0.4- 0.3- 000906 704 0.0 0.2- 000918 704 0.0 0.1- 001129 360 0.1- 0.5+ 000906 344 1.2+ 0.4- 000918 853 0.0 0.2+ 001129 360 0.3+ 0.0 ( ) -------- Rejected Obs.
