                         magnetospheric electric fields. In particular we show for the 
                         first time that the evening prereversal enhancement in the 
                         vertical drift/zonal electric field (PRE) and the consequent 
                         spread F (ESF) generation can be totally suppressed by penetration 
                         electric field of westward polarity arising from over-shielding 
                         processes. In contrast the undershielding PP electric field of 
                         eastward polarity is found to enhance the PRE and ESF in agreement 
                         with recent findings. These results are evaluated using 
                         collisional interchange instability growth rate model 
                         calculations. Citation: Abdu, M. A., E. A. Kherani, I. S. Batista,
