The following improved orbital elements, by S. Nakano, are from 105 observations 2006 Nov. 16 to 2007 Feb. 17. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.68 arc second. See the previous orbits in YC 2535, YC 2537. This orbit is same to HICQ 2007. Epoch = 2006 Apr. 15.0 TT T = 2006 Mar. 29.77483 +/- 0.03123 (m.e.) TT Peri. = 230.59203 +/- 0.00261 Node = 154.05933 +/- 0.00143 (2000.0) Inc. = 19.00523 +/- 0.00100 q = 1.6999599 +/- 0.0000602 AU e = 0.7068450 +/- 0.0000957 a = 5.7988425 +/- 0.0003285 AU n' = 0.07058170 +/- 0.00000600 P = 13.964 +/- 0.0011866 years (+/- 0.43 day) The predicted orbit for the 2020 return is as follows: T = 2020 Mar. 31.76570 TT Epoch = 2020 Mar. 12.0 TT Peri. = 232.38151 e = 0.7071859 Node = 152.25975 (2000.0) a = 5.8035348 AU Inc. = 18.55702 n'= 0.07049611 q = 1.6993569 AU P = 13.981 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2006/ 061121 850 1.1- 0.2- 061231 673 0.6+ 0.4- 061116 703 1.0- 0.1- 061121 850 1.2- 0.9+ 061231 673 0.9+ 0.1+ 061116 703 (2.5- 1.5+) 061123 204 0.3- 0.4+ 061231 673 0.3+ 0.0 061116 703 1.3- 0.6+ 061123 204 0.0 0.4- 2007/ 061116 703 1.0- 0.6- 061124 349 0.4+ 0.6+ 070113 349 0.6+ 0.7+ 061116 703 0.1- 0.9- 061124 349 0.5+ 0.7+ 070113 349 0.5+ 0.7+ 061116 703 0.6+ 0.6- 061211 118 0.8+ 0.5- 070113 349 0.6+ 0.7+ 061116 703 0.9+ 0.3- 061211 118 0.6- 0.1- 070114 349 0.4+ 0.2+ 061117 448 1.7- 1.1+ 061212 G96 0.8- 0.4- 070114 349 0.2+ 0.3+ 061117 448 0.6+ 0.1- 061212 G96 1.3- 0.5- 070114 349 0.1+ 0.2+ 061117 448 0.3+ 0.4- 061212 G96 0.2- 0.7- 070114 J95 1.0- 0.2+ 061117 711 0.4+ 0.4- 061214 215 0.6+ 0.5+ 070114 J95 1.1- 0.7+ 061117 711 1.0+ 0.3- 061216 246 0.3+ 0.4+ 070114 J95 0.8- 0.1- 061117 711 0.2- 0.0 061216 246 0.4- 0.1+ 070115 246 1.3+ 0.0 061117 G96 0.3+ 0.3+ 061216 246 0.4- 0.4+ 070115 246 0.5+ 0.1+ 061117 G96 0.8- 0.1+ 061216 246 0.9- 0.0 070115 246 0.8+ 0.9- 061117 G96 0.3+ 0.5- 061222 130 0.9+ 0.4- 070115 246 1.0+ 0.3+ 061117 G96 0.2+ 0.5- 061226 703 1.3- 0.0 070115 246 0.8+ 0.2+ 061118 J95 0.6- 0.3- 061226 703 (2.8- 0.9-) 070116 561 1.2+ 0.2- 061118 J95 0.3+ 0.5- 061226 703 1.6- 0.0 070116 561 0.4+ 0.9+ 061118 J95 0.0 0.0 061227 118 0.2- 0.5- 070116 561 1.2+ 1.4- 061118 711 0.4+ 0.0 061227 118 0.6+ 0.1- 070116 699 0.9- 0.0 061118 711 0.1- 0.1- 061227 118 0.5+ 0.2+ 070116 699 1.3- 0.5- 061118 711 0.4+ 0.1- 061227 246 1.6+ 0.2- 070116 699 1.1- 1.1- 061118 682 0.0 0.4+ 061227 246 1.2+ 0.4+ 070116 699 1.3- 1.1+ 061118 682 0.9- 0.3- 061227 246 0.1- 0.0 070116 322 (2.1- 1.6-) 061119 213 0.1+ 0.8+ 061227 246 0.3+ 1.3+ 070116 322 1.3- 0.0 061119 J95 0.4- 0.1+ 061227 246 0.1- 1.0+ 070116 322 (2.2- 0.3+) 061119 213 0.5+ 0.5- 061227 246 0.7- 0.0 070125 703 1.2- 0.3+ 061119 J95 0.8- 0.2- 061227 246 0.5+ 0.5+ 070125 703 1.7- 0.4+ 061119 213 0.8+ 0.7- 061230 246 0.9+ 0.1+ 070125 703 (4.3- 1.1-) 061119 682 0.1+ 0.3+ 061230 246 0.7+ 0.1+ 070125 703 0.3- 0.4- 061119 682 1.0- 0.6+ 061230 246 0.1- 0.0 070215 215 0.0 0.2- 061119 682 0.0 0.1+ 061230 246 0.3- 0.9+ 070217 703 1.8- 1.2- 061120 G96 0.4+ 0.3- 061230 246 0.4+ 0.0 070217 703 0.5+ 1.2- 061120 G96 1.0+ 0.4- 061230 246 0.5+ 0.4+ 070217 703 (0.9- 2.8-) 061120 G96 0.9+ 0.6- 061230 246 0.3+ 0.2+ 070217 703 0.8+ 0.9- 061120 G96 0.9+ 0.3- 061231 673 1.4+ 0.3- ( ) -------- Rejected Obs.
