OAA computing section circular NK 753 P/1998 VS24 (LINEAR)

The following improved orbital elements, by S. Nakano, are from 41 observations 1998 Oct. 24 to 1999 Jan. 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.67 arc second. Epoch = 1998 Nov. 3.0 TT T = 1998 Nov. 2.73969 +/- 0.42222 (m.e.) TT Peri. = 244.49747 +/- 0.07780 Node = 159.20546 +/- 0.00509 (2000.0) Inc. = 5.03127 +/- 0.00019 q = 3.4053810 +/- 0.0000797 AU e = 0.2439523 +/- 0.0000441 a = 4.5041880 +/- 0.0000629 AU n' = 0.10310490 +/- 0.00000216 P = 9.559 +/- 0.0002003 years (+/- 0.07 day) The predicted orbit for the 2008 return is as follows: T = 2008 May 24.78977 TT Epoch = 2008 May 14.0 TT Peri. = 244.39069 e = 0.2421576 Node = 159.18336 (2000.0) a = 4.5161677 AU Inc. = 5.02625 n'= 0.10269493 q = 3.4225432 AU P = 9.597 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 1998/ 981218 046 0.6- 0.6+ 981222 372 0.9- 0.4+ 981024 120 0.5- 0.3- 981218 557 0.4- 0.0 981223 402 1.5- 1.2- 981024 120 0.6- 0.0 981218 557 0.0 0.7- 981223 402 1.1- 0.2+ 981028 120 0.6- 0.2- 981218 557 0.2+ 0.3- 981223 402 0.3+ 1.1- 981028 120 1.0+ 1.2+ 981218 557 0.3- 0.1- 981223 402 (1.3+ 5.5-) 981110 704 0.5+ 0.8- 981218 557 0.2+ 0.3- 981224 402 0.5- 0.1+ 981110 704 0.4+ 0.3+ 981219 709 0.7+ 0.4+ 981224 402 0.8+ 0.3- 981110 704 0.3- 1.3+ 981219 709 0.4+ 0.3+ 981224 402 0.1+ 0.4+ 981110 704 0.3+ 1.6- 981219 709 0.1- 0.5+ 1999/ 981111 704 0.6+ 0.2- 981219 709 0.3+ 0.5+ 990113 360 0.0 0.5- 981111 704 0.2- 0.6+ 981219 658 0.1+ 0.1+ 990113 360 0.1- 0.3- 981111 704 0.4+ 0.3+ 981219 658 0.4+ 0.6+ 990113 360 0.0 0.6- 981126 120 1.1- 1.5- 981219 658 1.5- 0.8+ 990114 693 0.1+ 0.3+ 981126 120 0.1- 0.8- 981221 046 1.7+ 0.9+ 990114 693 0.0 0.1+ 981126 120 (1.7- 2.7-) 981221 046 1.7+ 0.7+ 990114 693 0.0 0.0 ( ) -------- Rejected Obs.
