Nakano Note (Nakano wa Kangaeru noda) NK 3988 P/2016 J1 - B (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 53 observations 2016 Apr. 14 to Aug. 4. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.32 arc second. Epoch = 2016 June 21.0 TT T = 2016 June 24.09566 +/- 0.02779 (m.e.) TT Peri. = 46.57030 +/- 0.00839 Node = 199.85611 +/- 0.00042 (2000.0) Inc. = 14.33141 +/- 0.00015 q = 2.4480933 +/- 0.0000135 AU e = 0.2282183 +/- 0.0000079 a = 3.1720021 +/- 0.0000368 AU n' = 0.17446322 +/- 0.00000303 P = 5.649 +/- 0.0000983 years The predicted orbit for the 2022 return is as follows: T = 2022 Feb. 20.50322 TT Epoch = 2022 Mar. 2.0 TT Peri. = 46.96896 e = 0.2276982 Node = 199.81126 (2000.0) a = 3.1720404 AU Inc. = 14.32998 n'= 0.17446006 q = 2.4497724 AU P = 5.649 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2016/ 160508 H01 0.1+ 0.3- 160612 695 0.2+ 0.3- 160304 F51(79.3- 0.8-) 160511 568 0.1+ 0.1+ 160731 Z18 0.3+ 0.2- 160304 F51(79.0- 0.8-) 160511 568 0.1+ 0.2- 160731 Z18 0.2+ 0.2- 160414 F51 0.0 0.3- 160511 568 0.1+ 0.0 160731 Z18 0.1+ 0.1+ 160414 F51 0.7- 0.6+ 160511 568 0.0 0.0 160731 Z18 0.1+ 0.2- 160414 F51 0.3- 0.5- 160515 Z18 0.0 0.0 160804 568 0.0 0.0 160414 F51 0.0 0.1+ 160515 Z18 0.0 0.0 160804 568 0.0 0.1+ 160506 H06 1.7- 0.8- 160515 Z18 0.1+ 0.0 160804 568 0.2- 0.2+ 160506 H06 1.4- 0.5- 160515 Z18 0.2+ 0.1- 160804 568 0.2- 0.0 160506 H06 1.3- 0.3- 160515 Z18 0.1+ 0.1- 160804 568 0.2- 0.1+ 160506 568 0.1+ 0.1+ 160529 Z18 0.0 0.1+ 160804 568 0.1- 0.1+ 160506 568 0.0 0.1+ 160529 Z18 0.1- 0.1+ 160804 568 0.1- 0.1+ 160507 568 0.0 0.2+ 160529 Z18 0.1- 0.1+ 160804 568 0.2- 0.1+ 160507 568 0.1+ 0.1+ 160529 Z18 0.1- 0.1+ 160804 568 0.1+ 0.1+ 160507 568 0.1+ 0.1+ 160529 Z18 0.1- 0.1+ 160804 568 0.4+ 0.0 160508 H01 0.1- 0.1+ 160606 695 0.0 0.0 160804 568 0.3+ 0.0 160508 H01 0.0 0.0 160607 695 0.1+ 0.4- 160804 568 0.4- 0.1+ 160508 H01 0.1+ 0.2+ 160609 695 0.4- 0.0 160804 568 0.1+ 0.1- 160508 H01 0.1+ 0.2- 160611 695 0.2- 0.1- ( ) -------- Rejected Obs.
