The following improved orbital elements, by S. Nakano, are from 81 observations 1995 Jan. 8 to 1996 Jan. 21. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.63 arc second. Epoch = 1993 Aug. 1.0 TT T = 1993 Aug. 17.31199 +/- 0.01928 (m.e.) TT Peri. = 295.92304 +/- 0.00347 Node = 116.01687 +/- 0.00006 (2000.0) Inc. = 19.87552 +/- 0.00013 q = 4.0823744 +/- 0.0001199 AU e = 0.3081262 +/- 0.0000254 a = 5.9004611 +/- 0.0000471 AU n' = 0.06876622 +/- 0.00000082 P = 14.333 +/- 0.0001715 years (+/- 0.06 day) The predicted orbit for the 2007 return is as follows: T = 2007 Dec. 3.30529 TT Epoch = 2007 Dec. 6.0 TT Peri. = 295.46154 e = 0.3078906 Node = 115.85163 (2000.0) a = 5.9050529 AU Inc. = 19.87444 n'= 0.06868603 q = 4.0869425 AU P = 14.349 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 1995/ 950126 360 0.8+ 1.2+ 950207 691 0.1+ 0.1+ 950108 691 0.0 0.0 950126 360 0.4+ 0.3- 950207 658 (2.1- 0.3-) 950108 691 0.5- 0.5- 950127 691 0.6- 0.4- 950207 691 0.1- 0.1- 950108 691 0.6- 0.3- 950127 691 0.5- 0.1- 950207 658 1.5- 0.8- 950108 691 0.0 0.7- 950127 691 0.3- 0.4- 950209 413 0.1- 0.5+ 950108 691 0.3- 0.7- 950127 104 0.7+ 0.6- 950209 413 0.4+ 0.0 950108 691 0.2- 0.8- 950127 104 0.4+ 0.7+ 950220 413 0.0 0.3- 950109 691 0.2- 0.6- 950127 104 0.1+ 1.4+ 950220 413 0.2+ 0.2- 950109 691 0.1- 0.6- 950128 691 0.6+ 1.0+ 950221 360 0.4- 0.3- 950109 691 0.4- 0.5- 950128 691 0.8+ 0.6+ 950221 360 0.2+ 0.3+ 950109 691 0.4- 0.0 950128 691 1.4+ 1.1+ 950221 360 0.4+ 0.0 950110 897 (4.5- 0.4+) 950129 691 0.6- 0.1- 950223 658 0.2- 0.9- 950110 897 (3.1- 0.8+) 950129 691 0.4- 0.5- 950223 658 0.6- 0.9- 950110 897 (9.4- 6.1-) 950129 691 0.7- 0.3- 950224 360 0.1- 0.4- 950122 691 1.0+ 0.6+ 950129 385 0.4+ 0.5+ 950224 360 1.0- 1.3- 950122 691 1.1+ 0.3+ 950129 385 (2.0+ 1.3-) 950224 360 0.4- 0.1- 950123 691 0.1- 0.3+ 950130 691 0.2+ 0.1+ 950305 691 0.6+ 0.2+ 950123 691 0.1+ 0.2- 950130 691 0.3+ 0.0 950305 691 0.3+ 0.6+ 950123 691 0.8+ 0.2+ 950130 691 0.1+ 0.6+ 950320 360 (2.1- 1.4-) 950123 691 0.8- 0.2+ 950131 372 (3.3- 1.0+) 950320 360 0.1- 1.5- 950124 658 0.1+ 0.7+ 950131 372 (2.7- 0.4-) 950527 691 0.4- 0.4- 950124 658 0.2- 0.6+ 950201 413 0.1- 0.2- 950527 691 0.7+ 0.1- 950124 658 0.3+ 0.2+ 950201 104 0.8+ 1.5+ 950527 691 0.1+ 1.0- 950124 658 1.2+ 0.1+ 950201 104 0.1+ 0.6+ 951228 691 0.6- 0.7+ 950125 372 1.5- 1.1- 950201 104 0.2+ 0.5- 951228 691 0.6- 0.6+ 950125 372 0.8- 0.6- 950204 691 0.6- 0.2+ 1996/ 950125 887 0.7- 0.4+ 950204 691 0.3- 0.2+ 960121 691 0.8+ 0.4- 950125 887 1.8+ 0.5- 950204 691 0.5- 0.3- 960121 691 0.2+ 0.3+ 950125 887 1.4+ 1.0+ 950206 587 0.3- 0.3- 960121 691 0.3+ 0.3- 950125 887 0.3+ 0.8+ 950206 587 0.5- 1.0+ 950126 360 0.6+ 0.2+ 950207 658 1.8- 0.0 ( ) -------- Rejected Obs.
