                         generated by the electric current systems that flow in the 
                         ionosphere are superimposed to the normal Earth Magnetic Field due 
                         to the main field generated at the Earths core and to the 
                         variations due to magnetospheric sources. Regarding to that 
                         variation from ionospheric sources, the equatorial electrojet is 
                         the main source of the H-component variations along to the dip 
                         equator. In latitudes away distant from the dip equator, we expect 
                         the effect to be reduced, resting the Solar Quiet (Sq) E-Region 
                         system influence only. In the present work we intend to analyze 
                         the H-component of the magnetic field in magnetically quiet days, 
                         registered at three magnetic stations that cover regions close, 
                         close apart and away from the dip equator: S{\~a}o Lu{\'{\i}}s 
                         (2.33° S, 44.20°), Eus{\'e}bio (3.89°S, 38.44°O) and S{\~a}o 
                         Martinho da Serra (29.43° S, 53.80° W), respectively. We will show 
                         a statistical analysis of the H-component variations of the 
                         magnetic field at these three latitudes including a comparative 
                         study of the difference between the mean values measured at each 
                         minute and the local midnight value. Wee will also show the 
                         evolution of the dip angle at the three stations. The Dst magnetic 
                         index was used to classify magnetic activity.",
