The following improved orbital elements, by S. Nakano, are from 35 observations 2005 Nov. 1 to 2006 Apr. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.34 arc second. Epoch = 2005 Aug. 18.0 TT T = 2005 Aug. 12.56655 +/- 0.00054 (m.e.) TT Peri. = 357.31590 +/- 0.00029 Node = 129.73888 +/- 0.00010 (2000.0) Inc. = 15.62200 +/- 0.00004 q = 2.3450749 +/- 0.0000049 AU e = 0.4785776 +/- 0.0000107 a = 4.4974571 +/- 0.0000206 AU n' = 0.10333645 +/- 0.00000071 P = 9.538 +/- 0.0000654 years The predicted orbit for the 2015 return is as follows: T = 2015 Apr. 27.46202 TT Epoch = 2015 Apr. 8.0 TT Peri. = 0.43846 e = 0.4701467 Node = 127.65547 (2000.0) a = 4.5674181 AU Inc. = 16.10099 n'= 0.10097129 q = 2.4200617 AU P = 9.761 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2005/ 051104 568 0.1+ 0.1- 051113 568 0.1+ 0.1- 051101 568 0.0 0.1+ 051104 568 0.0 0.1- 051201 204 1.0- 0.0 051101 568 0.0 0.0 051104 568 0.2+ 0.0 051201 204 0.2- 0.0 051101 568 0.1+ 0.1- 051108 204 0.5+ 0.1+ 051229 568 0.1- 0.0 051101 568 0.1+ 0.0 051111 568 0.1+ 0.0 051229 568 0.1- 0.0 051102 568 0.1- 0.0 051111 568 0.1+ 0.1+ 051229 568 0.0 0.1- 051102 568 0.2- 0.0 051111 568 0.2+ 0.0 2006/ 051102 568 0.1- 0.1- 051112 204 0.3- 0.3- 060402 204 0.0 0.1- 051102 568 0.1- 0.1+ 051113 568 0.1+ 0.1- 060402 204 0.3+ 0.4- 051103 568 0.3- 0.3+ 051113 568 0.1+ 0.0 060428 568 0.0 0.0 051103 568 0.3- 0.3+ 051113 568 0.2+ 0.1- 060428 568 0.0 0.0 051103 568 0.0 0.1+ 051113 568 0.1+ 0.0 051104 568 0.1- 0.0 051113 568 0.0 0.1- ( ) -------- Rejected Obs.
