Nakano Note (Nakano wa Kangaeru noda) NK 5241 P/2024 C2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 65 observations 2023 Dec. 25 to 2024 Apr. 30. 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 5350. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 11.04516 +/- 0.97292 (m.e.) TT Peri. = 87.56816 +/- 0.04512 Node = 66.44355 +/- 0.00139 (2000.0) Inc. = 27.28439 +/- 0.00024 q = 8.9911756 +/- 0.0007187 AU e = 0.4457098 +/- 0.0001300 a = 16.2210629 +/- 0.0040203 AU n' = 0.01508638 +/- 0.00000561 P = 65.331 +/- 0.0242879 years (+/- 8.87 days) The predicted orbit for the 2089 return is as follows: T = 2089 Dec. 30.95849 TT Epoch = 2089 Dec. 15.0 TT Peri. = 87.63463 e = 0.4449892 Node = 66.46924 (2000.0) a = 16.2217316 AU Inc. = 27.28137 n'= 0.01508545 q = 9.0032359 AU P = 65.335 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2023/ 240201 F52 0.0 0.1+ 240204 Z41 0.1- 0.2+ 231225 F52 0.2- 0.1- 240201 F52 0.3+ 0.2- 240204 Z41 0.6- 0.2+ 231225 F52 0.0 0.4+ 240201 F52 0.1- 0.0 240208 O46 0.4- 0.2- 231225 F52 0.4- 0.1+ 240201 F52 0.2+ 0.1- 240208 O46 0.2- 0.1+ 2024/ 240201 G00 0.2- 0.3+ 240208 O46 0.1+ 0.1+ 240105 F52 0.2- 0.2+ 240201 G00 0.1+ 0.2- 240208 O46 0.3+ 0.0 240106 F51 0.2+ 0.1+ 240201 G00 0.2- 0.7- 240211 U69 0.0 0.4- 240106 F51 0.1+ 0.1- 240201 204 0.2+ 0.0 240211 U69 0.1- 0.1- 240106 F51 0.1+ 0.0 240201 204 0.3+ 0.2- 240211 204 0.1+ 0.7+ 240106 F51 0.1+ 0.0 240201 L06 0.3- 0.3- 240211 204 0.4+ 0.2+ 240106 F51 0.2+ 0.0 240201 L06 0.5- 0.1+ 240226 F51 0.0 0.0 240106 F51 0.0 0.0 240202 L06 0.4- 0.2+ 240226 F51 0.1+ 0.1+ 240120 F52 0.2+ 0.0 240202 L01 0.4+ 0.4- 240226 F51 0.3+ 0.1- 240121 F52 0.2+ 0.0 240203 L01 0.6- 0.3- 240226 F51 0.5- 0.2- 240122 F51 0.2+ 0.1+ 240203 L01 0.1- 0.4+ 240303 K77 0.8- 0.0 240122 F51 0.2+ 0.3- 240203 L01 0.2+ 0.4+ 240303 K77 0.3- 1.3+ 240122 F51 0.2+ 0.1- 240203 L01 0.3+ 0.7+ 240308 K77 0.2+ 0.4- 240122 F51 0.2+ 0.0 240203 K63 0.0 1.0- 240308 K77 0.6+ 0.4- 240123 F52 0.1+ 0.0 240203 K63 0.1+ 0.2+ 240430 215 0.2+ 0.0 240123 F52 0.2- 0.0 240203 K63 0.0 0.1+ 240430 215 0.1- 0.0 240123 F52 0.2+ 0.0 240204 W62 0.2- 0.1- 240430 215 0.1+ 0.0 240123 F52 0.1+ 0.2- 240204 W62 0.1- 0.1- 240201 F52 0.2+ 0.1- 240204 W62 0.1- 0.0 ( ) -------- Rejected Obs.
