The following improved orbital elements, by S. Nakano, are from 79 observations 2003 Nov. 20 to 2004 Feb. 10. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.59 arc second. Epoch = 2003 Aug. 29.0 TT T = 2003 Sept.16.83894 +/- 0.00812 (m.e.) TT Peri. = 9.13972 +/- 0.00526 Node = 43.55514 +/- 0.00125 (2000.0) Inc. = 14.72705 +/- 0.00043 q = 1.8808059 +/- 0.0000378 AU e = 0.4366702 +/- 0.0000398 a = 3.3387297 +/- 0.0000735 AU n' = 0.16155938 +/- 0.00000534 P = 6.101 +/- 0.0002015 years (+/- 0.07 day) The predicted orbit for the 2010 return is as follows: T = 2010 Jan. 31.95244 TT Epoch = 2010 Feb. 13.0 TT Peri. = 16.09246 e = 0.4163630 Node = 40.52841 (2000.0) a = 3.4092014 AU Inc. = 13.43598 n'= 0.15657596 q = 1.9897360 AU P = 6.295 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2003/ 031215 J95 0.4+ 0.2+ 031219 372 1.0+ 0.7+ 031120 704 0.2- 0.2- 031215 J95 0.5+ 0.4- 031219 372 1.2+ 0.7+ 031120 704 (2.1+ 3.7+) 031215 A50 0.7- 0.4+ 031219 372 0.1+ 0.1+ 031120 704 0.5+ 0.7+ 031215 A50 (2.3- 1.2+) 031221 372 0.2+ 1.3+ 031204 704 0.2+ 0.2+ 031216 854 (2.3+ 1.5+) 031224 213 (1.6- 2.3-) 031204 704 0.4+ 1.3- 031216 854 0.7- 0.2- 031224 213 1.9- 1.8- 031204 704 1.1- 0.1- 031216 854 (3.1- 0.4+) 031224 213 0.4+ 0.3+ 031204 704 0.6- 1.1- 031216 673 0.9+ 0.2- 031228 341 1.4- 0.9- 031205 704 1.0- 0.6- 031216 673 0.6+ 0.1+ 031228 341 1.6+ 1.1+ 031205 704 0.7+ 0.4- 031216 673 0.5+ 0.2+ 031228 341 1.5+ 0.6+ 031205 704 0.1+ 0.5+ 031216 673 0.4+ 0.3+ 031228 360 0.1- 0.1- 031214 644 0.5+ 0.6+ 031216 673 0.1+ 0.2+ 031228 360 0.1+ 0.4+ 031214 644 0.4+ 0.4+ 031216 673 0.4+ 0.5+ 031228 360 0.3- 0.0 031214 644 0.8+ 0.1- 031216 926 0.2+ 0.4+ 031230 704 0.5- 0.6- 031214 J95 0.1- 0.7- 031216 926 0.7- 0.3+ 031230 704 0.7+ 0.1- 031214 J95 0.5- 0.0 031216 926 0.8- 0.7- 031230 704 0.0 0.3- 031214 J95 0.4- 0.9- 031216 J95 0.3+ 0.1- 031230 704 0.8+ 0.1+ 031215 966 0.1- 0.1+ 031216 J95 0.4+ 0.0 031230 372 0.5+ 0.0 031215 J95 0.8+ 0.4- 031216 J95 0.6- 0.0 2004/ 031215 966 0.4+ 0.1+ 031217 446 1.3- 0.8- 040101 213 0.6- 0.6- 031215 J95 0.1- 0.2- 031217 446 0.3- 1.0+ 040101 213 0.6- 0.2+ 031215 J95 0.5- 0.3+ 031217 673 0.4+ 0.7+ 040110 104 1.1- 0.2+ 031215 926 0.3- 0.2+ 031217 673 0.1- 0.4+ 040110 104 0.2+ 0.4- 031215 926 0.8- 0.1- 031217 926 0.6+ 0.1- 040110 104 0.0 0.9- 031215 926 0.1- 0.0 031217 926 0.1- 0.0 040117 360 0.0 0.4- 031215 A50 0.5+ 0.5- 031217 649 0.4- 0.1- 040117 360 0.1- 0.2+ 031215 J95 0.1- 0.5- 031217 926 0.1- 0.4+ 040117 360 0.5+ 0.1- 031215 A50 0.1- 0.3+ 031217 701 0.6- 1.0+ 040210 204 0.1- 0.5+ 031215 A50 0.7- 0.1+ 031217 701 0.0 0.2- 040215 204 (1.8- 5.1+) ( ) -------- Rejected Obs.
