The following improved orbital elements, by S. Nakano, are from 53 observations 2002 Aug. 17 to Oct. 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.73 arc second. Epoch = 2002 July 25.0 TT T = 2002 July 15.98368 +/- 0.00428 (m.e.) TT Peri. = 184.74681 +/- 0.00276 Node = 174.10042 +/- 0.00182 (2000.0) Inc. = 36.36676 +/- 0.00115 q = 1.5213090 +/- 0.0000460 AU e = 0.5695874 +/- 0.0000924 a = 3.5345365 +/- 0.0002169 AU n' = 0.14832193 +/- 0.00001365 P = 6.645 +/- 0.0006116 years (+/- 0.22 day) The predicted orbit for the 2009 return is as follows: T = 2009 Mar. 20.95209 TT Epoch = 2009 Mar. 30.0 TT Peri. = 185.01962 e = 0.5639210 Node = 173.99608 (2000.0) a = 3.5571240 AU Inc. = 36.28007 n'= 0.14691142 q = 1.5511872 AU P = 6.709 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2002/ 020818 658 0.2+ 0.6+ 020910 349 0.1+ 0.5+ 020817 699 (2.6- 1.1+) 020818 848 0.9- 0.7+ 020912 360 0.2+ 0.1- 020817 699 1.0- 0.2+ 020818 848 0.8- 0.1- 020912 360 0.2+ 0.4- 020817 699 (4.4- 0.7+) 020818 848 0.0 0.4- 020918 360 0.7+ 0.5- 020817 699 (4.4- 0.1-) 020819 848 1.2+ 0.8- 020918 360 0.3+ 0.0 020818 046 0.5+ 0.2+ 020819 848 0.3- 1.0- 020919 349 0.0 0.3+ 020818 046 0.2+ 0.5- 020819 848 0.2- 0.4- 020919 349 0.5+ 1.2- 020818 046 0.9+ 0.2+ 020819 413 0.8+ 0.2- 020919 349 (0.2- 2.2-) 020818 046 0.5- 0.3+ 020819 413 0.8+ 0.2- 020923 340 1.5- 1.7+ 020818 046 1.1- 0.0 020819 413 0.8+ 0.2+ 020923 340 (2.5- 1.0-) 020818 046 0.1+ 0.3- 020820 349 0.0 0.5- 020923 340 (9.0- 0.9+) 020818 046 0.5+ 0.4+ 020820 349 0.5+ 0.2- 020923 340 (1.9- 2.1+) 020818 118 0.7+ 1.8+ 020820 349 0.0 0.0 020930 118 0.3- 0.9+ 020818 118 1.2- 0.2+ 020820 349 0.3+ 0.8- 020930 118 0.0 1.9+ 020818 118 0.8- 0.4+ 020821 170 0.1- 0.8+ 021010 699 1.0- 0.7+ 020818 118 0.5+ 0.2- 020821 170 0.8- 0.9- 021010 699 1.1- 0.1- 020818 620 (4.7- 1.2+) 020830 349 (2.1- 0.7+) 021010 699 0.5- 0.9+ 020818 620 (2.3+ 0.1+) 020830 349 (2.8- 0.4-) 021010 699 0.1- 0.4+ 020818 620 (2.1- 0.4-) 020830 349 0.5- 1.4+ 021014 428 0.9+ 0.6- 020818 620 (1.3+ 2.3+) 020831 J95 (2.2- 1.4+) 021014 360 0.4+ 1.3- 020818 620 1.1- 1.4+ 020831 J95 0.7+ 1.7- 021014 360 0.5+ 1.0- 020818 658 0.5+ 0.4- 020910 349 0.3+ 1.3- 021014 360 0.9+ 0.3- 020818 658 0.1+ 0.2- 020910 349 0.5- 0.6- ( ) -------- Rejected Obs.
