The following improved orbital elements, by S. Nakano, are from 96 observations 2002 June 11 to 2003 Oct. 20. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.64 arc second. Epoch = 2002 Oct. 13.0 TT T = 2002 Oct. 26.81789 +/- 0.19674 (m.e.) TT Peri. = 37.29773 +/- 0.02562 Node = 264.58967 +/- 0.00054 (2000.0) Inc. = 11.39748 +/- 0.00024 q = 4.2396652 +/- 0.0001433 AU e = 0.4716951 +/- 0.0000591 a = 8.0250352 +/- 0.0001168 AU n' = 0.04335445 +/- 0.00000095 P = 22.734 +/- 0.0004964 years (+/- 0.18 day) The predicted orbit for the 2025 return is as follows: T = 2025 Aug. 6.96286 TT Epoch = 2025 July 24.0 TT Peri. = 37.69080 e = 0.4712840 Node = 264.48421 (2000.0) a = 7.9990642 AU Inc. = 11.40010 n'= 0.04356576 q = 4.2292332 AU P = 22.623 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2002/ 030825 673 0.5+ 0.8+ 030914 213 0.6+ 0.3- 020611 644 0.8+ 0.4+ 030825 673 0.7+ 0.9+ 030914 213 0.2+ 0.2- 020611 644 0.3- 0.2- 030825 673 0.6+ 1.0+ 030916 A03 (9.5- 0.9-) 020611 644 0.3- 0.6- 030825 621 0.6- 1.5- 030917 A03 (0.9+ 4.5+) 2003/ 030826 621 0.5+ 1.6- 030918 204 0.1+ 0.1- 030823 644 0.4- 0.1+ 030826 621 0.2+ 0.1- 030918 204 1.0- 0.0 030823 644 0.5- 0.4+ 030826 621 1.3+ 1.7- 030918 204 0.1+ 0.3+ 030823 644 0.1- 0.5+ 030826 621 1.0+ 0.9- 030927 H41 0.7+ 0.1+ 030823 246 0.1- 0.5+ 030831 807 0.1- 0.0 030928 691 0.1+ 0.1- 030823 246 0.1- 0.7+ 030831 807 0.1- 0.0 030928 691 0.1+ 0.1- 030823 246 0.8- 0.1+ 030831 807 0.1+ 0.2+ 030928 H41 0.1- 0.5- 030823 246 0.3- 0.3+ 030831 807 0.4- 1.1+ 030928 691 0.1- 0.6+ 030823 246 0.7- 0.4+ 030831 807 0.1+ 1.0+ 030928 H41 1.2- 1.2- 030823 587 1.5+ 0.8- 030831 807 0.1+ 0.5+ 030928 118 (0.2+ 2.2+) 030823 151 0.5+ 0.6+ 030901 673 0.6+ 0.0 030928 118 1.0- 0.4+ 030823 151 0.0 0.5+ 030901 673 0.3- 0.3+ 030930 360 0.7- 0.3- 030823 151 0.4+ 0.4+ 030901 673 0.2+ 0.5+ 030930 360 1.1- 0.1+ 030823 151 0.6+ 0.9+ 030901 673 1.5+ 0.7+ 030930 360 0.1- 0.7- 030823 587 1.4- 0.7- 030901 673 0.9+ 0.7+ 031002 A33 (7.3+ 1.9-) 030823 587 1.0- 0.8- 030901 673 0.8+ 0.8+ 031009 170 0.8- 0.5- 030823 106 0.4- 0.9- 030901 673 0.3+ 0.4+ 031009 170 0.7+ 0.3- 030823 106 1.0- 0.8- 030901 673 0.4+ 0.6+ 031009 170 0.9+ 0.8- 030823 106 0.0 0.3- 030903 215 0.5- 0.0 031009 170 0.7+ 0.5- 030824 859 0.5- 0.0 030904 360 0.1- 0.3- 031017 360 0.3+ 0.7+ 030824 J87 0.4- 0.0 030904 360 0.2+ 0.5- 031017 360 0.6+ 0.4+ 030824 J87 (3.0- 3.1-) 030904 360 0.0 0.0 031017 360 0.3+ 0.0 030824 246 0.6- 0.0 030905 204 1.3+ 1.6- 031018 715 0.1+ 0.2+ 030824 246 0.7- 0.4+ 030905 246 0.2- 0.4+ 031018 715 0.2+ 0.2- 030824 246 (2.1- 0.8-) 030905 246 0.9- 0.2+ 031018 715 0.1+ 0.4- 030824 246 0.4- 0.0 030905 246 0.7- 0.3+ 031019 360 0.6+ 0.4+ 030824 621 1.4- 0.6- 030905 246 (2.1- 0.6-) 031019 360 0.3+ 0.2+ 030824 621 0.9- 0.8+ 030913 715 0.2- 0.4- 031019 360 0.4+ 0.7+ 030824 621 0.4+ 0.1- 030913 715 (2.2- 1.0-) 031020 213 1.5- 0.8- 030824 621 0.5- 0.4+ 030913 715 0.2+ 0.1- 031020 213 0.1- 1.3- 030824 621 0.8- 0.7+ 030914 213 1.2+ 0.1- 030825 673 0.7+ 0.6+ 030914 213 0.9+ 0.3- ( ) -------- Rejected Obs.
