OAA computing section circular NK 884 P/2002 B1 (LINEAR)
The following improved orbital elements, by S. Nakano, are from 89 observations 2001 Nov. 8 to 2002 May 31. 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 = 2002 May 6.0 TT T = 2002 Apr. 20.01124 +/- 0.00146 (m.e.) TT Peri. = 76.16224 +/- 0.00063 Node = 58.18242 +/- 0.00009 (2000.0) Inc. = 51.02011 +/- 0.00009 q = 2.2711285 +/- 0.0000079 AU e = 0.7709048 +/- 0.0000094 a = 9.9134685 +/- 0.0000414 AU n' = 0.03157662 +/- 0.00000020 P = 31.213 +/- 0.0001953 years (+/- 0.07 day) The predicted orbit for the 2033 return is as follows: T = 2033 Apr. 14.58397 TT Epoch = 2033 May 3.0 TT Peri. = 76.01309 e = 0.7701414 Node = 58.14944 (2000.0) a = 9.8846601 AU Inc. = 51.04049 n'= 0.03171476 q = 2.2720741 AU P = 31.077 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2001/ 020201 704 (0.6- 2.0+) 020204 587 0.1- 0.4- 011108 704 0.1+ 0.3- 020201 704 1.6- 0.8+ 020206 341 0.1- 0.1+ 011108 704 0.2+ 0.9+ 020201 118 1.5- 0.0 020206 341 0.6+ 0.4+ 011108 704 0.1+ 0.4+ 020201 118 1.3- 0.0 020206 402 0.4+ 0.4+ 011108 704 0.3+ 0.4- 020201 118 0.3+ 0.4+ 020206 402 0.4+ 0.5+ 2002/ 020201 118 0.7+ 0.1- 020206 402 0.0 0.7+ 020126 704 0.1- 0.3+ 020201 118 0.4+ 0.1- 020209 170 0.6- 0.1+ 020126 704 0.8- 0.3+ 020201 046 0.3+ 0.4- 020209 170 1.4+ 0.6+ 020126 704 0.2- 0.5+ 020201 046 0.3+ 0.4- 020215 360 0.2- 0.3+ 020126 704 0.6- 0.2+ 020201 046 0.3+ 0.5- 020215 360 0.0 0.1+ 020126 704 1.5- 1.1+ 020201 046 0.7+ 0.9- 020216 118 0.0 0.5+ 020129 461 0.4+ 0.2- 020201 046 0.5+ 1.2- 020216 118 0.1- 0.5+ 020129 461 0.1- 0.1+ 020202 118 0.5+ 0.7- 020216 118 0.0 0.3+ 020129 461 0.1+ 0.1+ 020202 118 0.7+ 1.1- 020309 367 0.8- 0.7- 020129 461 0.1- 0.2+ 020202 118 1.0+ 0.6- 020309 367 0.0 0.0 020129 118 0.3+ 0.1+ 020202 118 1.1- 0.7+ 020309 367 0.0 0.7+ 020129 118 0.5+ 0.0 020202 118 0.9- 0.9+ 020311 118 0.8+ 1.0- 020129 118 0.7+ 0.2- 020202 118 0.8- 0.5+ 020311 118 0.0 1.1- 020129 046 0.7- 0.0 020203 670 0.0 0.3- 020311 118 0.4+ 1.3- 020129 046 0.4- 0.3- 020203 670 0.1+ 0.3- 020311 215 0.5+ 0.4- 020129 046 0.4- 0.9- 020204 046 (2.0+ 1.6-) 020311 215 0.3+ 0.6- 020129 046 1.2- 1.0- 020204 046 1.2+ 1.3- 020311 204 0.3- 0.5+ 020130 966 0.1- 0.4- 020204 046 0.8+ 0.4- 020311 204 0.0 0.6+ 020130 966 0.3- 0.1- 020204 046 0.0 0.4- 020311 204 0.5+ 0.8+ 020131 201 0.1+ 0.4+ 020204 118 0.1- 0.3- 020311 204 0.3+ 0.7+ 020131 201 0.3+ 0.2+ 020204 118 0.4+ 0.1- 020315 921 (2.2- 1.1+) 020131 201 0.1+ 0.4+ 020204 106 0.5+ 0.3- 020315 921 0.3+ 1.5+ 020131 966 0.5- 0.6+ 020204 106 0.4+ 0.0 020315 921 (5.7- 2.7+) 020131 966 0.5- 0.3- 020204 118 0.0 0.0 020410 921 0.9- 0.4- 020131 966 0.1+ 0.3- 020204 106 0.0 0.2- 020531 215 0.4+ 0.3+ 020201 704 1.6+ 0.3- 020204 118 0.2- 0.1+ 020531 215 0.5+ 0.4+ 020201 704 0.7- 0.9+ 020204 587 0.2+ 0.0 ( ) -------- Rejected Obs.
