             abstract = "CMEs ejected from the sun into the interplanetary space are 
                         gigantic clouds of ionized gas, that after a few hours or days may 
                         eventually hit the Earth and cause, among other effects, 
                         geomagnetic storms. Geomagnetic storms are disturbances caused by 
                         gusts in the solar wind, injecting a substantial quantity of 
                         energy into the magnetosphere. In this work we analyze intense 
                         geomagnetic storms (Dst < -100nT) using images of the solar corona 
                         made by the Large Angle and Spectroscopic Coronagraph (LASCO) and 
                         images of the solar disk made by the Extreme Ultraviolet Imaging 
                         Telescope (EIT), both aboard the Solar and Heliospheric 
                         Observatory (SOHO). Observations of plasma and interplanetary 
                         magnetic field at one astronomic unit (1 AU), obtained by the 
                         Advanced Composition Explorer (ACE) were also used. We analyze 
                         high energy cosmic ray observations obtained by the high energy 
                         50GeV Muon Multidirectional Telescope of the Brazilian Southern

                         Research Center for identifying Forbush decreases in the cosmic 
                         ray intensity. The objective of this work is to study intense 
                         geomagnetic storms, that occurred in a relatively small time 
                         interval, in order to identify their solar origin, interplanetary 
                         counterparts and cosmic ray modulation near the Earth. This study 
                         is important for the study of energetic cosmic rays modulation due 
                         to a subsequent chain of interplanetary disturbances.",
