The following improved orbital elements, by S. Nakano, are from 133 observations 2001 Feb. 24 to 2002 July 22. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.69 arc second. This is same orbit in HICQ 2013. Epoch = 2000 Dec. 2.0 TT T = 2000 Nov. 22.46528 +/- 0.01508 (m.e.) TT Peri. = 80.79120 +/- 0.00238 Node = 92.83375 +/- 0.00024 (2000.0) Inc. = 19.08746 +/- 0.00004 q = 4.1532527 +/- 0.0000414 AU e = 0.3556193 +/- 0.0000097 a = 6.4453401 +/- 0.0000181 AU n' = 0.06023311 +/- 0.00000025 P = 16.363 +/- 0.0000687 years The predicted orbit for the 2017 return is as follows: T = 2017 May 5.68314 TT Epoch = 2017 May 7.0 TT Peri. = 80.51569 e = 0.3596012 Node = 92.65346 (2000.0) a = 6.5342333 AU Inc. = 19.05405 n'= 0.05900817 q = 4.1845150 AU P = 16.703 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2001/ 010402 046 0.5- 0.5+ 010520 046 0.7- 0.3- 010224 608 0.4+ 0.3- 010402 046 0.2+ 0.6+ 010520 046 1.5- 0.6- 010324 608 1.4+ 0.9+ 010402 046 0.4+ 0.7+ 010520 046 0.5- 0.0 010324 608 1.2+ 1.6+ 010403 402 0.4- 0.1- 010521 699 0.8- 0.3- 010324 608 1.3+ 1.4+ 010403 402 0.2- 0.1+ 010521 699 0.4+ 0.9- 010325 859 0.7+ 0.3+ 010403 402 1.4- 0.2+ 010521 699 0.5- 0.6- 010325 859 0.1- 0.5- 010404 402 0.6- 0.5- 010521 699 0.5+ 1.5- 010325 859 0.2+ 0.7+ 010404 402 0.9- 0.3- 010525 118 1.1- 0.6+ 010325 854 1.9+ 0.3+ 010404 402 0.0 0.2- 010525 118 1.2+ 1.2- 010325 854 0.2- 0.5- 010413 372 0.6- 0.6+ 010525 118 0.2+ 0.1- 010326 649 0.0 0.2+ 010414 170 1.2- 0.2+ 010607 170 0.3- 1.2- 010326 649 1.1- 0.3+ 010414 170 0.0 0.0 010607 170 0.1- 0.9- 010326 649 0.0 0.4+ 010414 170 1.3+ 0.3- 010607 170 (3.2+ 0.3-) 010326 649 0.2+ 0.1+ 010414 170 1.4- 0.2- 010609 682 1.5+ 0.4- 010327 649 0.9+ 0.3+ 010415 372 1.6- 0.3+ 010609 682 0.7+ 0.2+ 010327 649 0.0 1.0+ 010419 341 0.1- 0.7+ 010611 360 0.9+ 0.2+ 010327 649 0.3- 0.5+ 010419 341 0.1- 0.3- 010611 360 0.7+ 0.7+ 010327 608 1.1+ 0.8- 010419 341 0.5- 0.5+ 010611 360 0.2- 0.1+ 010327 608 0.6+ 1.3- 010419 341 0.0 0.9- 010614 644 1.0+ 0.7+ 010327 608 0.5+ 0.9- 010419 372 0.1+ 0.4+ 010614 644 0.6+ 0.3- 010328 684 0.4- 0.2+ 010419 402 0.9+ 0.2- 010614 644 0.5+ 0.1- 010328 684 0.2- 0.1- 010419 402 1.1+ 0.9+ 010616 699 0.4+ 0.4+ 010328 850 1.2+ 0.5+ 010419 402 0.6+ 0.8- 010616 699 0.1+ 0.1- 010328 684 0.6- 0.1- 010419 360 0.2+ 0.5- 010616 699 0.6- 0.9+ 010328 850 (2.4+ 3.0+) 010419 360 0.4+ 0.6- 010616 699 0.6- 0.5+ 010328 422 (3.0- 2.5-) 010421 170 (3.6- 0.1-) 010616 170 (1.1+ 2.7-) 010328 422 (3.6- 1.2-) 010423 170 0.9- 0.2+ 010616 170 0.1+ 1.3- 010328 422 0.3- 0.5- 010425 170 (2.9- 1.4+) 010623 504 1.0+ 0.8+ 010328 046 1.5- 0.2+ 010426 118 0.4+ 1.2- 010623 504 0.5+ 0.4+ 010328 046 0.1- 0.5- 010426 118 0.2+ 0.2- 010623 504 0.4- 1.3+ 010328 046 0.1+ 0.4- 010428 170 0.2- 0.4- 010624 644 0.4+ 0.1- 010328 046 0.7- 0.5- 010428 170 1.9- 0.1+ 010624 644 0.1+ 0.2- 010328 046 0.5- 0.1+ 010429 046 1.0- 0.0 010624 644 0.3- 0.4- 010329 684 0.7- 0.1+ 010429 046 0.2- 0.1+ 010723 360 0.0 1.4+ 010329 684 0.5- 0.1+ 010429 046 0.3+ 0.3+ 010723 360 0.4+ 1.0+ 010329 608 1.2+ 1.1- 010502 682 0.0 1.8+ 010723 360 0.2- 1.4+ 010329 608 1.0+ 0.9- 010502 682 0.2+ 1.1+ 2002/ 010329 608 0.4+ 0.7- 010508 170 0.9- 0.2- 020508 608 0.9+ 0.6- 010331 360 0.1- 0.3- 010508 170 1.3- 0.3- 020508 608 1.2- 0.9+ 010331 360 0.0 0.4- 010508 170 1.7- 0.2- 020508 608 (0.6+ 2.3-) 010331 046 0.6+ 0.3+ 010510 118 0.6- 0.7- 020601 644 0.7+ 0.0 010331 046 0.3- 0.2+ 010510 118 0.4- 0.8- 020601 644 0.6- 0.4- 010331 046 0.0 0.4- 010511 170 0.7- 0.2- 020601 644 1.0- 0.2- 010331 046 0.3+ 0.1- 010512 360 0.7+ 0.3- 020609 644 0.9+ 0.9- 010401 867 0.6+ 0.3+ 010512 360 0.8+ 0.2- 020722 644 0.0 0.0 010401 867 0.2+ 0.2+ 010513 402 0.7+ 0.6- 020722 644 0.1+ 0.9+ 010401 867 0.1+ 0.5+ 010513 402 0.5- 0.8+ 020722 644 0.3+ 0.3- 010402 046 0.7- 0.2+ 010513 402 1.1+ 0.7+ ( ) -------- Rejected Obs.
