                         (gradient drift irregularities) detected with the 50 MHz 
                         backscatter coherent radar set at S{\~a}o Luis, Brazil (SLZ, 
                         2.3S, 44.2W) during the solar cycle 24. In this report we 
                         present the dependence of the vertical and zonal components of 
                         this electric field with the solar activity, based on the solar 
                         flux F10.7. For this study we consider the geomagnetically quiet 
                         days only (Kp \≤ 3+ ). A magnetic field-aligned-integrated 
                         conductivity model was developed for proving the conductivities, 
                         using the IRI-2007, the MISIS-2000, and the IGRF-11 models as 
                         input parameters for ionosphere, neutral atmosphere, and Earth 
                         magnetic field, respectively. The ion-neutron collision 
                         frequencies of all the species are combined through the momentum 
                         transfer collision frequency equation. The mean zonal component of 
                         the electric field, which normally ranged from 0.19 to 0.35 mV/m 
                         between the 8 and 18 h (LT) in the Brazilian sector, show a small 
                         dependency with the solar activity. Whereas the mean vertical 
                         component of the electric field, which normally ranges from 4.65 
                         to 10.12 mV/m, highlights the more pronounced dependency of the 
                         solar flux.",
