                         dynamic electron population within the outer Van Allen radiation 
                         belt, where electron energies range from several 10s to several 
                         1000s KeV. Geomagnetic storms and various solar wind-magnetosphere 
                         interaction processes including convection cause either dramatic 
                         particle flux increase or decreases. Here we analyze the 
                         occurrence of a drop out of ~ 0.04 4.5 MeV electron fluxes 
                         measured by NASA's Van Allen Probes, during a magnetic 
                         cloud-driven geomagnetic storm which started at September 12, 
                         2014. The ~3-day storm left a steady low flux of outer belt 
                         energetic electrons that lasted for twelve days. At higher energy 
                         levels, electron fluxes decreased by ~1 orders of magnitude 
                         throughout the vast region from L* ~3 to 6.6. To describe the 
                         physical mechanism associated to the loss observed at L* higher 
                         than 4, it was simulated electron trajectory using TS95 and 
                         self-consistent BATS-RUS models of magnetic field during the 
                         shock, the results are consistent with the magnetopause
