A new analytical technique for extracting the Boozer magnetic coordinates in axisymmetric MHD equilibria is described. The method is based upon the correspondence between the expansion of the flux function in torodial multipolar moments and the expansion in toroidal axisymmetric harmonics of the magnetic scalar potential chi(0). An example of calculation of Boozer magnetic coordinates is given for an experimental highly shaped beta equilibrium of DIIID.
