The following improved orbital elements, by S. Nakano, are from 92 observations 2023 Nov. 24 to 2024 Apr. 10. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.41 arc second. Residuals for 2024 Match/April observations were -15" for Right Ascension and +5" for Declination from an orbit in CH 2024. Epoch = 2023 Dec. 2.0 TT T = 2023 Nov. 29.73117 +/- 0.00379 (m.e.) TT Peri. = 51.42340 +/- 0.00196 Node = 78.85841 +/- 0.00043 (2000.0) Inc. = 6.38409 +/- 0.00002 q = 2.0797664 +/- 0.0000105 AU e = 0.4450329 +/- 0.0000123 a = 3.7475490 +/- 0.0000851 AU n' = 0.13585733 +/- 0.00000463 P = 7.255 +/- 0.0002471 years (+/- 0.09 day) The predicted orbit for the 2031 return is as follows: T = 2031 Mar. 9.25008 TT Epoch = 2031 Feb. 23.0 TT Peri. = 51.59419 e = 0.4442403 Node = 78.78942 (2000.0) a = 3.7527893 AU Inc. = 6.37955 n'= 0.13557287 q = 2.0856490 AU P = 7.270 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2023/ 240109 Q11 0.2+ 0.1+ 240303 Q11 0.3- 0.4+ 231124 F52 0.3+ 0.3- 240111 G96 0.3- 0.1- 240303 Q11 0.3- 0.3+ 231124 F52 0.5+ 0.0 240111 G96 0.4- 0.1- 240303 Q11 0.5- 0.3+ 231124 F52 0.1+ 0.0 240111 G96 0.2- 0.3+ 240306 F51 0.1+ 0.1- 231124 F52 0.3+ 0.3- 240111 G96 0.1- 0.1- 240306 F51 0.1+ 0.1- 231217 G96 0.2- 0.3- 240121 F52 0.3+ 0.2- 240306 F51 0.1+ 0.1- 231217 G96 0.3- 0.1- 240121 F52 0.6+ 0.0 240306 F51 0.1+ 0.1- 231217 G96 0.9+ 0.2+ 240121 F52 0.4+ 0.1- 240307 G96 0.5- 0.1- 231217 G96 0.5+ 0.2- 240121 F52 0.7+ 0.2- 240307 G96 0.4- 0.0 231217 G96 0.6- 0.3- 240205 215 0.3+ 0.2+ 240307 G96 0.5- 0.0 231217 G96 0.3- 0.1+ 240205 215 0.1- 0.7+ 240307 G96 0.6- 0.2- 231217 G96 0.1+ 0.1- 240205 215 (0.7- 2.8+) 240312 Q62 0.1+ 0.3+ 231217 F52 0.2+ 0.1- 240209 F52 0.4+ 0.2- 240312 Q62 0.0 0.2+ 231217 F52 0.3+ 0.1- 240209 F52 0.4+ 0.2- 240315 903 1.0- 1.2+ 231217 F52 0.5+ 0.3- 240209 F52 0.4+ 0.1- 240315 903 0.9- 1.0+ 231217 F52 0.5+ 0.4- 240209 F52 0.4+ 0.2- 240315 903 0.5- 0.2+ 231218 L01 0.4- 0.2+ 240209 F52 0.5+ 0.2- 240318 G96 0.6- 0.1- 231218 L01 0.6+ 0.6- 240209 F52 0.6+ 0.3- 240318 G96 0.1- 0.4- 231218 L01 0.7+ 0.3- 240209 F52 0.6+ 0.1- 240318 G96 0.4- 0.6- 231218 G00 0.6- 0.7+ 240209 F52 0.6+ 0.1- 240318 G96 0.3- 0.1- 231218 G00 0.5- 0.1+ 240209 Q11 0.4+ 0.4+ 240318 F52 0.2+ 0.1- 231219 G00 1.0- 0.8+ 240209 Q11 0.5+ 0.5+ 240318 F52 0.1+ 0.0 231219 G00 1.2- 0.7+ 240218 F52 0.5- 0.6+ 240318 F52 0.2+ 0.1+ 231219 G00 (2.2- 1.7+) 240218 F52 0.4+ 0.2- 240318 F52 0.0 0.2- 2024/ 240218 F52 0.2+ 0.1- 240331 F52 0.2+ 0.1- 240105 Q11 0.5- 0.6+ 240219 G96 0.3- 0.2- 240331 F52 0.0 0.2- 240105 Q11 0.6- 0.6+ 240219 G96 0.3- 0.0 240331 F52 0.2- 0.2- 240106 X03 0.9- 0.9- 240219 G96 0.1- 0.0 240331 F52 0.2+ 0.1- 240106 X03 0.6- 0.6+ 240219 G96 0.6- 0.4+ 240410 F52 0.3+ 0.1+ 240106 X03 0.9- 0.3- 240302 F51 0.3+ 0.3- 240410 F52 0.1- 0.1- 240106 X03 0.5+ 0.3- 240302 F51 0.3+ 0.1- 240410 F52 0.1+ 0.5+ 240109 Q11 0.3+ 0.0 240302 F51 0.1+ 0.1- 240410 F52 0.2- 0.3- ( ) -------- Rejected Obs.
