                         has long been known. Recent computations based on an eccentric 
                         geomagnetic dipole, as compared with archeomagnetic data obtained 
                         in South America, seem to indicate that the SAMA region has a 
                         periodic movement around the Earth with a period of about 2300 
                         years. We think that this evidence may contribute to a better 
                         understanding of the complex physical processes occurring in the 
                         Earth's liquid core, where the magnetic field originates.",
