                         the role played by a complex solar structure composed of a 
                         corotating interaction region (CIR) followed by solar wind 
                         Alfv{\'e}nic fluctuations on the magnetospheres nightside, 
                         equatorial electric field oscillations in the ultra-low-frequency 
                         range. A series of numerical experiments are performed employing 
                         synthetic solar wind inputs resembling those of a real CIR 
                         +Alfv{\'e}nic fluctuation event that reached Earths magnetosphere 
                         on 2003 April 20. The following is found: (i) Radial electric 
                         field component fluctuations are excited via magnetopause boundary 
                         motions driven either by solar wind density variations 
                         characteristic of CIRs or by solar wind Alfv{\'e}nic fluctuations 
                         with a given oscillation period. (ii) Azimuthal electric field 
                         component fluctuations nearer to Earth, that is, at radial 
                         distances R less than about 5RE (RE = 1 Earth radius), are 
                         apparently not related to either of the two types of sinusoidal 
                         solar wind Alfv{\'e}nic fluctuations used in this study featuring 
                         monochromatic frequencies of 0.833 mHz (20-minute period) and 
                         1.666 mHz (10-minute period). Instead, these innermost azimuthal 
                         component fluctuations show enhanced activity when inner 
                         magnetosphere convection increases as a result of a southward 
                         turning of the interplanetary magnetic field component Bz. (iii) 
                         Lastly, outermost (R \ 7 RE) azimuthal electric field 
                         oscillations weakly respond to monochromatic solar wind 
                         Alfv{\'e}nic fluctuations by showing power spectral density peaks 
                         at both driving frequencies, but only near the flanks of the 
                         magnetopause, thus suggesting that such oscillations are being 
                         excited also owing to magnetopause boundary motions driven by 
                         solar wind Alfv{\'e}nic fluctuations.",
