             abstract = "The variation of solar x-ray radiation follows a behavior similar 
                         to the solar cycle activity, which results in periodic 
                         disturbances on the Earths atmosphere. Among the most intense 
                         solar activity events are the solar flares: sudden, localized, 
                         transient increases in brightness caused by active regions near 
                         sunspots. The data analysis for investigation of this phenomenon 
                         can provide important information about the Magnetosphere, the 
                         Earth/Sun interaction, as well as events occurring in the 
                         Ionosphere which can, for instance, generate disturbances in 
                         telecommunications, small satellites or even in the Space Weather. 
                         In this work we are studying the characteristics of high-intensity 
                         flares (X class) and its effects on the Earth occurred during the 
                         solar cycle 23 (1996 - 2007). For this purpose, we utilize data of 
                         X-rays band (0.5 to 8 Å) from the GOES satellites (Geostationary 
                         Operational Environmental Satellites), as well as the equipments 
                         dedicated to study the Solar-Earth interactions at the Southern 
                         Space Observatory (SSO/CRS/INPE MCT), (29°S, 53°W, 480 m a.s.l.), 
                         S{\~a}o Martinho da Serra, RS, Brazil, such as riometer and 
                         magnetometer. With these tools, we search for any correlation 
                         between the solar activity and the ionospheric phenomenon, as the 
                         Sudden Ionospheric Disturbance (SID) and magnetic crochet, causing 
                         sudden changes in the ionospheric density and variations in the 
                         components of the geomagnetic field that allow us to infer about 
                         the disturbed currents in the ionosphere.",
