Nakano Note (Nakano wa Kangaeru noda) NK 5236 P/2023 Y2 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 84 observations 2022 Oct. 23 to 2024 Mar. 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.56 arc second. See the previous orbit in CBET 5329 (= NK 5163). Epoch = 2023 Aug. 4.0 TT T = 2023 Aug. 9.80607 +/- 0.00170 (m.e.) TT Peri. = 16.78977 +/- 0.00061 Node = 79.23113 +/- 0.00039 (2000.0) Inc. = 6.99280 +/- 0.00003 q = 2.2758749 +/- 0.0000016 AU e = 0.3921261 +/- 0.0000124 a = 3.7439919 +/- 0.0000763 AU n' = 0.13605099 +/- 0.00000416 P = 7.244 +/- 0.0002216 years (+/- 0.08 day) The predicted orbit for the 2030 return is as follows: T = 2030 Nov. 13.87608 TT Epoch = 2030 Oct. 26.0 TT Peri. = 16.91531 e = 0.3907783 Node = 79.19476 (2000.0) a = 3.7527544 AU Inc. = 6.98620 n'= 0.13557476 q = 2.2862595 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(") 2022/ 231218 I81 0.7- 0.5+ 240112 L06 0.1+ 0.4+ 221023 F52 0.2- 0.3- 231218 L01 0.1+ 0.1+ 240112 L06 0.5+ 0.4+ 221023 F52 0.4- 0.4- 231218 L01 0.3+ 0.0 240115 Q11 0.2- 0.1- 221023 F52 0.2- 0.6- 231218 I81 0.8- 0.5+ 240115 Q11 0.2- 0.3- 221220 G96 0.5+ 0.5+ 231218 L01 0.3- 0.0 240115 Q11 0.1- 0.1- 221220 G96 0.3+ 0.3+ 231220 W62 0.3- 1.2+ 240205 215 1.2- 1.7+ 221220 G96 0.3+ 0.5+ 231220 W62 0.4- 1.2+ 240205 215 1.1- 1.1+ 221220 G96 0.0 0.4+ 231220 W62 0.5- 1.3+ 240205 215 1.9- 0.1- 2023/ 231221 P87 1.2- 0.2- 240207 Q11 0.4- 0.0 231213 F51 0.7+ 0.3- 231221 P87 1.8- 0.1+ 240207 Q11 0.5- 0.1+ 231213 F51 0.6+ 0.3- 2024/ 240210 F52 0.9+ 0.3- 231213 F51 0.2+ 0.0 240104 204 0.2- 0.3+ 240210 F52 0.8+ 0.2- 231213 F51 0.5+ 0.0 240104 204 0.5- 0.3+ 240210 F52 0.7+ 0.2- 231217 G96 0.3+ 0.4- 240106 M45 (2.5+ 0.4-) 240210 F52 0.7+ 0.1- 231217 G96 0.8+ 0.3- 240106 M45 (0.1+ 2.6-) 240210 F52 0.9+ 0.3- 231217 G96 0.7+ 0.6- 240106 M45 0.2- 0.3- 240210 F52 0.7+ 0.4- 231217 G96 0.1+ 0.3- 240107 X03 1.3- 0.1- 240210 F52 0.9+ 0.2- 231217 I52 0.4+ 0.5- 240107 X03 0.2- 0.6+ 240210 F52 0.8+ 0.2- 231217 I52 0.7- 0.1- 240107 X03 (2.8- 0.8+) 240306 F51 0.5+ 0.1- 231217 I52 0.1+ 0.2+ 240107 X03 (2.4+ 0.3+) 240306 F51 0.2+ 0.0 231217 I52 0.6- 0.1- 240109 L38 0.4- 1.0- 240306 F51 0.4+ 0.0 231217 F52 0.2+ 0.2- 240110 L38 0.3- 0.5- 240306 F51 0.2+ 0.3- 231217 F52 0.4+ 0.2- 240110 G01 0.8- 1.7- 240309 Q11 0.1- 0.1+ 231217 F52 0.4+ 0.3- 240110 M49 0.8+ 0.9- 240309 Q11 0.0 0.2+ 231217 F52 0.5+ 0.3- 240110 M49 0.1+ 0.7+ 240314 V00 0.2+ 0.1- 231217 Q62 0.4- 0.0 240110 G01 0.2+ 1.3- 240314 V00 0.1- 0.1+ 231217 Q62 0.0 0.2- 240110 M49 0.1- 1.0+ 240314 V00 0.1+ 0.1- 231218 G00 0.8+ 0.2- 240110 G01 (1.1- 3.7-) 240314 V00 0.1+ 0.1- 231218 L01 0.0 0.1- 240111 Q11 0.3+ 0.2- 240314 Q11 0.1- 0.1+ 231218 G00 0.2+ 0.8+ 240111 Q11 0.3+ 0.2- 240314 Q11 0.1- 0.2+ 231218 I81 0.1+ 0.3+ 240112 L06 0.5- 0.4+ ( ) -------- Rejected Obs.
