Nakano Note (Nakano wa Kangaeru noda) NK 2876 P/2011 V1 (Boattini)
The following improved orbital elements, by S. Nakano, are from 25 observations 2011 Oct. 22 to Nov. 20. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.40 arc second. Epoch = 2011 Apr. 29.0 TT T = 2011 May 11.86630 +/- 0.04451 (m.e.) TT Peri. = 259.52700 +/- 0.01487 Node = 60.08237 +/- 0.00976 (2000.0) Inc. = 7.39983 +/- 0.00383 q = 1.7093225 +/- 0.0002902 AU e = 0.5551673 +/- 0.0004235 a = 3.8426185 +/- 0.0009671 AU n' = 0.13084682 +/- 0.00004940 P = 7.533 +/- 0.0028437 years (+/- 1.04 days) The predicted orbit for the 2018 return is as follows: T = 2018 Sept.30.88353 TT Epoch = 2018 Oct. 9.0 TT Peri. = 269.24408 e = 0.5501698 Node = 46.79361 (2000.0) a = 3.8502688 AU Inc. = 7.38296 n'= 0.13045703 q = 1.7319672 AU P = 7.555 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2011/ 111101 G96 0.5- 0.2- 111102 291 0.1- 0.1+ 111022 G96 1.1- 0.1+ 111101 G96 0.2- 0.2+ 111102 H06 0.5- 0.6- 111022 G96 0.3- 0.1- 111101 G96 0.1+ 0.4- 111102 H06 0.0 0.2- 111022 G96 1.1+ 0.1+ 111101 G96 1.1+ 0.0 111102 H06 0.4+ 0.0 111022 G96 0.3+ 0.1- 111101 B18 0.3+ 0.4+ 111103 H06 0.1- 0.1- 111101 G96 0.0 0.4- 111101 B18 0.5+ 0.2+ 111103 H06 0.2- 0.3+ 111101 G96 0.1+ 0.3+ 111101 B18 0.1- 0.7+ 111120 C32 0.7+ 0.1- 111101 G96 0.4- 0.3- 111102 291 0.2- 0.3+ 111120 C32 0.7- 0.1+ 111101 G96 0.2+ 0.2- 111102 291 0.3- 0.1+ ( ) -------- Rejected Obs.
