Nakano Note (Nakano wa Kangaeru noda) NK 4603 P/2021 V2 (Fuls)
The following improved orbital elements, by S. Nakano, are from 90 observations 2021 Aug. 7 to 2022 Jan. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.28 arc second. See an orbit in CBET 5068. Epoch = 2023 Jan. 16.0 TT T = 2023 Jan. 21.41932 +/- 0.00264 (m.e.) TT Peri. = 259.82389 +/- 0.00121 Node = 232.28341 +/- 0.00008 (2000.0) Inc. = 12.69375 +/- 0.00008 q = 3.4968463 +/- 0.0000680 AU e = 0.6137183 +/- 0.0000310 a = 9.0525816 +/- 0.0007484 AU n' = 0.03618640 +/- 0.00000449 P = 27.237 +/- 0.0033777 years (+/- 1.23 days) The predicted orbit for the 2050 return is as follows: T = 2050 June 22.38426 TT Epoch = 2050 June 3.0 TT Peri. = 259.25338 e = 0.6219789 Node = 231.97147 (2000.0) a = 9.3385578 AU Inc. = 12.63978 n'= 0.03453698 q = 3.5301723 AU P = 28.538 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2021/ 211108 204 0.1- 0.3+ 211130 G96 0.1+ 0.0 210807 F51 0.2+ 0.1- 211108 204 0.5- 0.1+ 211130 G96 0.1- 0.0 210807 F51 0.1- 0.1+ 211108 587 0.1- 0.4- 211130 G96 0.1+ 0.1- 210807 F51 0.1- 0.1+ 211108 587 0.1+ 0.2- 211130 G96 0.1- 0.0 210816 F51 0.0 0.0 211108 H06 0.2- 0.1+ 211201 X03 0.0 0.1- 210816 F51 0.0 0.1- 211108 H06 0.2- 0.2+ 211201 X03 0.2- 0.1- 210820 F51 0.0 0.0 211108 D29 0.0 0.1- 211201 X03 0.1- 0.0 210820 F51 0.0 0.0 211108 D29 0.9+ 0.4- 211222 Q21 0.1- 0.5+ 210820 F51 0.0 0.1+ 211108 D29 0.4+ 0.7- 211222 Q21 1.6+ 0.4+ 210820 F51 0.0 0.0 211108 A77 0.5- 0.3+ 211225 T08 0.2- 0.2+ 211028 F52 0.1- 0.1+ 211108 A77 0.3- 0.1- 211225 T08 0.3+ 0.7- 211028 F52 0.1+ 0.1- 211108 A77 0.3- 0.2- 211225 T08 0.4+ 0.2- 211028 F52 0.0 0.1+ 211108 215 0.3- 0.0 211225 T08 0.3- 0.1- 211028 F52 0.1- 0.0 211108 215 0.4- 0.0 211227 G96 0.1- 0.1- 211031 F52 0.2+ 0.0 211108 215 0.8- 0.0 211227 G96 0.1- 0.0 211031 F52 0.2+ 0.0 211109 Q11 0.4- 0.3+ 211227 G96 0.1- 0.0 211031 F52 0.2+ 0.0 211109 Q11 0.4- 0.4+ 211227 G96 0.2- 0.1- 211031 F52 0.2+ 0.0 211109 Q11 0.4- 0.4+ 211227 D29 0.2- 0.1+ 211107 G96 0.3- 0.0 211111 349 1.1- 0.2- 211227 D29 0.1- 0.1+ 211107 G96 0.2- 0.2- 211111 349 0.8- 0.1+ 211227 D29 0.1- 0.1- 211107 G96 0.3- 0.1+ 211113 Z10 0.1+ 0.2+ 211228 D29 0.2- 0.2- 211107 G96 0.2- 0.1+ 211113 Z10 0.2- 0.2+ 211228 D29 0.2- 0.1+ 211107 F52 0.0 0.0 211113 Z10 0.5+ 0.8+ 211228 D29 0.1- 0.1+ 211107 F52 0.0 0.0 211115 G96 0.1- 0.1+ 211229 D29 0.3+ 0.6- 211107 F52 0.0 0.0 211115 G96 0.3- 0.1- 211229 D29 0.5+ 0.4+ 211107 F52 0.0 0.0 211115 G96 0.1- 0.1+ 211229 D29 0.4- 0.5+ 211107 G96 0.3- 0.0 211115 G96 0.7- 0.2- 2022/ 211107 G96 0.1- 0.0 211127 F52 0.1+ 0.0 220101 D29 0.0 0.2- 211107 G96 0.2- 0.1+ 211127 F52 0.1+ 0.0 220101 D29 0.3- 0.1+ 211107 G96 0.3- 0.2- 211127 F52 0.0 0.1- 220101 D29 0.1- 0.2- 211108 587 0.1- 0.0 211127 F52 0.0 0.0 ( ) -------- Rejected Obs.
