The following improved orbital elements, by S. Nakano, are from 40 observations 1999 Feb. 18 to 1999 July 7. 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 = 1998 Sept.24.0 TT T = 1998 Oct. 1.32594 +/- 0.26711 (m.e.) TT Peri. = 161.37111 +/- 0.07584 Node = 5.95459 +/- 0.07511 (2000.0) Inc. = 18.72003 +/- 0.00994 q = 3.9084642 +/- 0.0001805 AU e = 0.1350787 +/- 0.0000359 a = 4.5188668 +/- 0.0000621 AU n' = 0.10260293 +/- 0.00000212 P = 9.606 +/- 0.0001981 years (+/- 0.07 day) The predicted orbit for the 2008 return is as follows: T = 2008 May 11.03138 TT Epoch = 2008 May 14.0 TT Peri. = 161.76498 e = 0.1358906 Node = 5.84263 (2000.0) a = 4.5070938 AU Inc. = 18.73091 n'= 0.10300521 q = 3.8946219 AU P = 9.569 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 1999/ 990414 704 0.2- 0.3+ 990516 046 0.2- 0.8- 990218 120 0.2+ 0.0 990414 704 0.8+ 0.2+ 990516 046 0.1+ 0.2+ 990219 120 1.9+ 0.3- 990415 704 0.4+ 0.0 990516 046 0.6+ 0.8- 990219 120 (4.3+ 1.6+) 990415 704 1.0+ 0.2- 990520 402 0.1- 0.6+ 990224 120 1.5- 0.6+ 990415 704 0.9- 0.4+ 990520 402 0.1- 0.5+ 990224 120 0.3- 0.8- 990415 704 0.0 0.4- 990520 402 1.7- 0.1- 990406 704 0.2- 0.1+ 990415 704 (2.9- 0.4-) 990520 360 0.7- 0.0 990406 704 0.8- 0.4+ 990514 860 0.3- 0.3- 990520 360 1.1- 0.3- 990406 704 1.1- 0.1- 990514 860 1.4+ 0.5+ 990520 360 0.7- 0.3- 990406 704 0.0 0.5- 990514 860 1.3+ 1.0+ 990614 867 0.1- 0.5+ 990406 704 0.4- 0.3- 990514 734 0.3+ 1.1- 990614 867 0.4- 0.1- 990410 699 0.4+ 0.4+ 990514 719 (1.2+ 2.4+) 990614 867 0.2- 0.2+ 990410 699 0.1- 0.7+ 990514 734 1.4+ 0.3+ 990707 360 0.2- 0.3- 990410 699 0.4+ 0.1+ 990514 734 0.6+ 0.1+ 990707 360 0.1+ 0.3- 990414 704 0.0 0.5- 990514 719 (3.2- 2.2-) 990707 360 0.7+ 0.1- ( ) -------- Rejected Obs.
