OAA computing section circular NK 1471 P/2005 V1 (Bernardi)
The following improved orbital elements, by S. Nakano, are from 37 observations 2005 Nov. 1 to 2006 July 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.34 arc second. See an orbit in NK 1353. Epoch = 2005 Aug. 18.0 TT T = 2005 Aug. 12.56663 +/- 0.00044 (m.e.) TT Peri. = 357.31610 +/- 0.00018 Node = 129.73880 +/- 0.00006 (2000.0) Inc. = 15.62197 +/- 0.00002 q = 2.3450765 +/- 0.0000039 AU e = 0.4785682 +/- 0.0000056 a = 4.4973795 +/- 0.0000108 AU n' = 0.10333912 +/- 0.00000037 P = 9.538 +/- 0.0000344 years The predicted orbit for the 2015 return is as follows: T = 2015 Apr. 27.37331 TT Epoch = 2015 Apr. 8.0 TT Peri. = 0.43875 e = 0.4701362 Node = 127.65524 (2000.0) a = 4.5673493 AU Inc. = 16.10101 n'= 0.10097358 q = 2.4200732 AU P = 9.761 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2005/ 051104 568 0.1+ 0.1- 051113 568 0.1+ 0.1- 051101 568 0.0 0.0 051104 568 0.0 0.1- 051201 204 1.0- 0.1+ 051101 568 0.0 0.0 051104 568 0.1+ 0.0 051201 204 0.2- 0.0 051101 568 0.1+ 0.1- 051108 204 0.5+ 0.1+ 051229 568 0.1- 0.1+ 051101 568 0.1+ 0.1- 051111 568 0.1+ 0.0 051229 568 0.1- 0.0 051102 568 0.1- 0.1- 051111 568 0.1+ 0.1+ 051229 568 0.0 0.0 051102 568 0.2- 0.0 051111 568 0.2+ 0.0 2006/ 051102 568 0.2- 0.1- 051112 204 0.3- 0.3- 060402 204 0.1- 0.0 051102 568 0.1- 0.0 051113 568 0.1+ 0.1- 060402 204 0.2+ 0.4- 051103 568 0.3- 0.3+ 051113 568 0.1+ 0.0 060428 568 0.0 0.0 051103 568 0.3- 0.2+ 051113 568 0.2+ 0.1- 060428 568 0.0 0.0 051103 568 0.0 0.1+ 051113 568 0.1+ 0.0 060726 568 0.0 0.1- 051104 568 0.1- 0.0 051113 568 0.1+ 0.1- 060726 568 0.0 0.0 ( ) -------- Rejected Obs.
