             abstract = "Disturbances in the interplanetary space near the Earth are 
                         closely related to solar variability and its variety of eruptive 
                         phenomena, such as CMEs and CIRs. Many authors have shown that 
                         they are the interplanetary origin of geomagnetic storms. Such 
                         geomagnetic phenomena can cause damage to technological systems, 
                         both in space and on the ground. Structures ejected from the Sun 
                         can modulate high-energy cosmic rays that reach the Earths 
                         Atmosphere. Ground based high-energy cosmic ray (muons) detectors 
                         can detect solar-related anisotropy effects. With suitable 
                         analysis, they can be used to observe signatures around 8 hours 
                         prior the disturbance arrival in the Earths magnetosphere. A 
                         multidirectional high-energy > 50 GeV muon telescope was installed 
                         and is operational at the Southern Space Observatory - 
                         OES/CRS/CIE/INPE - MCT or SSO, as part of an international network 
                         which aims to study and forecast geomagnetic storms. Cosmic rays 
                         are also observed in a different energy range by Spaceship Earth, 
                         a neutron monitor network. The objective of this work is to 
                         present technical aspects of the SSOs muons telescope observations 
                         and to analyze the data related to geomagnetic storms. Comparison 
                         with the Spaceship Earth neutron monitor data is also presented. 
                         To identify and study interplanetary geoeffective structures we 
                         use plasma and magnetic field data from ACE spacecraft. 
                         Geomagnetic storms were identified using the Dst index. We show 
                         some cosmic ray (muons and neutrons) decreases associated with 
                         geomagnetic storms and its interplanetary origin.",
