Nakano Note (Nakano wa Kangaeru noda) NK 5240 P/2024 C1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 64 observations 2023 Dec. 12 to 2024 May 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.24 arc second. See an orbit in CBET 5348. Epoch = 2024 Sept. 7.0 TT T = 2024 Aug. 30.87596 +/- 0.05373 (m.e.) TT Peri. = 94.46568 +/- 0.00825 Node = 83.81077 +/- 0.00057 (2000.0) Inc. = 14.22691 +/- 0.00005 q = 4.4129730 +/- 0.0001037 AU e = 0.5822988 +/- 0.0000437 a = 10.5649032 +/- 0.0011330 AU n' = 0.02870158 +/- 0.00000462 P = 34.340 +/- 0.0055242 years (+/- 2.02 days) The predicted orbit for the 2059 return is as follows: T = 2059 Mar. 17.36458 TT Epoch = 2059 Mar. 8.0 TT Peri. = 94.58662 e = 0.5840551 Node = 83.71608 (2000.0) a = 10.6206544 AU Inc. = 14.21883 n'= 0.02847588 q = 4.4176065 AU P = 34.612 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2023/ 240210 F52 0.1+ 0.1- 240317 658 0.2- 0.0 231212 F52 0.2- 0.1+ 240210 F52 0.2+ 0.2- 240317 658 0.4- 0.2- 231212 F52 0.3+ 0.3+ 240211 U94 0.7- 0.2+ 240404 F52 0.1+ 0.2+ 231212 F52 0.1- 0.5+ 240211 U94 0.6- 0.2+ 240404 F52 0.1+ 0.0 2024/ 240213 F52 0.2+ 0.0 240404 F52 0.0 0.0 240120 F52 0.1+ 0.1- 240213 F52 0.2+ 0.1- 240404 F52 0.1+ 0.1+ 240120 F52 0.1- 0.1- 240213 F52 0.2+ 0.0 240426 215 0.5- 0.1- 240120 F52 0.2- 0.1- 240213 F52 0.1+ 0.1- 240426 215 0.4- 0.2- 240120 F52 0.0 0.1- 240213 F52 0.1+ 0.1- 240426 215 0.1- 0.9- 240121 F51 0.2+ 0.2- 240215 L01 0.2- 0.0 240502 F52 0.0 0.0 240121 F51 0.1+ 0.3- 240215 L01 0.4- 0.1+ 240502 F52 0.0 0.0 240204 F52 0.0 0.1- 240215 L01 0.2+ 0.1- 240502 F52 0.1+ 0.1- 240204 F52 0.0 0.3- 240215 L01 0.1- 0.4- 240502 F52 0.0 0.0 240204 F52 0.1- 0.0 240215 204 0.2+ 0.0 240502 F52 0.1- 0.1+ 240204 F52 0.1+ 0.1- 240215 204 0.2- 0.1- 240502 F52 0.0 0.1+ 240209 F52 0.1+ 0.1- 240308 K77 0.8- 1.1+ 240502 F52 0.1+ 0.0 240209 F52 0.1+ 0.1- 240308 K77 (7.8- 2.1+) 240502 F52 0.1+ 0.1- 240209 F52 0.1+ 0.1- 240313 G96 0.2- 0.0 240514 G96 0.2+ 0.0 240209 F52 0.1+ 0.0 240313 G96 0.2- 0.0 240514 G96 0.1- 0.1- 240209 F52 0.4+ 0.1- 240313 G96 0.0 0.2- 240514 G96 0.2- 0.5- 240209 F52 0.1+ 0.1- 240313 G96 0.0 0.1- 240514 G96 0.2- 0.5+ 240210 F52 0.0 0.1- 240317 658 0.2- 0.2+ 240210 F52 0.1- 0.2+ 240317 658 0.2- 0.1+ ( ) -------- Rejected Obs.
