Nakano Note (Nakano wa Kangaeru noda) NK 4024 P/2019 T6 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 140 observations 2019 Oct. 8 to Dec. 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. Epoch = 2019 Nov. 13.0 TT T = 2019 Nov. 7.76194 +/- 0.00291 (m.e.) TT Peri. = 328.91035 +/- 0.00145 Node = 71.31148 +/- 0.00032 (2000.0) Inc. = 18.69647 +/- 0.00028 q = 2.0518831 +/- 0.0000158 AU e = 0.6221930 +/- 0.0000115 a = 5.4310348 +/- 0.0001703 AU n' = 0.07787180 +/- 0.00000366 P = 12.657 +/- 0.0005951 years (+/- 0.22 day) The predicted orbit for the 2032 return is as follows: T = 2032 July 21.28593 TT Epoch = 2032 July 27.0 TT Peri. = 329.28800 e = 0.6223785 Node = 71.23334 (2000.0) a = 5.4372194 AU Inc. = 18.68198 n'= 0.07773897 q = 2.0532110 AU P = 12.678 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2019/ 191017 291 1.2- 0.3+ 191024 850 0.8- 0.3+ 191008 F52 0.3+ 0.1- 191017 291 0.5- 0.2+ 191024 T08 0.4- 0.3+ 191008 F52 0.4+ 0.0 191018 D06 0.4+ 0.0 191024 T08 0.6- 0.1+ 191008 F52 0.5+ 0.1- 191018 D06 0.4+ 0.4+ 191024 T08 0.3- 0.3+ 191008 F52 0.3+ 0.1- 191018 D06 0.1- 0.6- 191024 T08 (2.2- 1.2+) 191009 L01 0.0 0.3- 191019 691 (2.0- 0.4+) 191024 C95 0.3- 0.1- 191009 L01 0.3+ 0.2+ 191019 691 1.2- 0.2+ 191024 C95 0.3+ 0.1+ 191009 L01 0.6+ 0.5- 191019 691 1.3- 0.3+ 191026 703 0.3- 0.2- 191009 L01 0.3+ 0.0 191019 F51 0.1+ 0.0 191026 703 1.6- 0.0 191009 L01 0.1- 0.2- 191019 F51 0.1+ 0.1- 191026 703 0.2- 0.1+ 191009 L01 0.7+ 0.4- 191019 F51 0.2+ 0.0 191026 703 0.6- 0.1+ 191009 I52 0.3+ 0.0 191019 K88 0.5- 0.5+ 191026 215 0.5+ 0.8+ 191009 I52 0.2- 0.5+ 191019 K88 0.3- 0.3+ 191026 215 1.3+ 0.2+ 191009 I52 0.3- 0.3+ 191019 K88 0.3- 0.2+ 191026 215 0.0 0.2- 191009 I52 1.2- 1.1+ 191019 K88 0.6- 0.5+ 191030 Q11 0.3- 0.3+ 191009 Q62 0.2- 0.4+ 191020 E10 0.4- 0.3+ 191030 Q11 0.4- 0.4+ 191009 Q62 0.4- 0.1- 191020 E10 0.2- 0.2+ 191030 Q11 0.2- 0.5+ 191009 Q62 0.2- 0.2- 191020 E10 0.3- 0.1+ 191101 703 1.7- 0.2+ 191009 094 0.2+ 0.1- 191020 E10 0.2- 0.1+ 191101 703 0.5- 0.8+ 191009 094 0.7+ 0.0 191021 691 1.0- 0.5+ 191101 703 0.9- 0.4- 191009 094 0.3- 0.0 191021 691 1.1- 0.8+ 191101 703 0.8- 0.6+ 191009 Z84 0.1- 0.1- 191021 691 1.1- 0.6+ 191102 F52 0.1+ 0.0 191009 Z84 0.0 0.1- 191022 K63 0.2- 0.3+ 191102 F52 0.1+ 0.0 191009 Z84 0.0 0.1- 191022 K63 0.1- 0.0 191102 F52 0.1+ 0.0 191009 Z84 0.0 0.3- 191022 K63 0.6+ 0.3- 191102 F52 0.1+ 0.0 191010 A77 0.4+ 0.2+ 191023 204 0.3- 0.0 191118 703 0.1+ 0.4- 191010 A77 1.2- 0.7+ 191023 204 0.2- 0.0 191118 703 0.1+ 0.8- 191010 A77 1.0- 0.5+ 191023 204 0.4- 0.3- 191118 703 0.5- 0.7- 191010 691 1.6- 0.4+ 191023 I47 0.6- 0.3- 191118 703 1.0+ 0.0 191010 691 1.9- 0.4+ 191023 I47 0.5- 0.1- 191125 F52 0.0 0.1- 191010 691 0.9- 0.2+ 191023 I47 0.1- 0.1- 191125 F52 0.1- 0.2- 191011 K87 0.1+ 0.2+ 191023 703 0.1- 0.1+ 191125 F52 0.0 0.1- 191011 K87 0.0 0.0 191023 703 0.8- 0.2+ 191126 D95 0.1+ 0.3+ 191011 K87 0.6- 0.4- 191023 703 1.1- 0.0 191126 D95 0.2+ 0.6+ 191011 G40 0.3- 0.1- 191023 703 0.9- 0.0 191126 D95 0.4- 0.2- 191011 G40 0.3- 0.3- 191023 F52 0.0 0.1+ 191129 Q11 0.2+ 0.0 191011 I52 1.8- 1.2- 191023 F52 0.2+ 0.2- 191129 Q11 0.3+ 0.1+ 191011 I52 1.0- 0.4- 191023 F52 0.1+ 0.1+ 191129 Q11 0.3+ 0.0 191011 I52 0.1+ 0.3+ 191023 F52 0.1+ 0.1- 191130 K77 (0.8+ 2.2+) 191011 G96 0.0 0.2- 191023 568 0.2+ 0.0 191130 K77 (0.4+ 2.8+) 191011 G96 0.1- 0.4- 191023 568 0.2+ 0.0 191202 A77 0.1+ 0.1+ 191011 G96 0.1- 0.1- 191023 568 0.2+ 0.1- 191202 A77 0.3+ 0.0 191011 G96 0.0 0.1- 191023 K88 0.1+ 0.1+ 191202 A77 0.2+ 0.1+ 191013 585 (0.5+ 2.2+) 191023 K88 0.1+ 0.2+ 191227 Q11 0.3+ 0.0 191013 585 (1.4+ 2.3+) 191024 850 0.3- 0.6+ 191227 Q11 0.4+ 0.0 191016 L01 0.4+ 0.1- 191024 850 0.3- 0.2+ 191227 Q11 0.1+ 0.0 191016 L01 0.2- 0.1- 191024 850 0.6- 0.0 191227 A77 0.2+ 0.7+ 191016 L01 0.3+ 0.3+ 191024 850 0.2+ 0.2- 191227 A77 0.2+ 0.9+ 191016 L01 0.5+ 0.1+ 191024 850 0.4- 0.8+ 191227 A77 0.3- 0.6+ ( ) -------- Rejected Obs.
