             abstract = "During the declining phase of the solar cycle 23, the solar 
                         activity intensified to high levels, especially from mid-October 
                         through early November 2003, where there were some of the most 
                         intense solar flares measured in 1.0 to 8.0A X-rays range, already 
                         registered. The Nov 4 event is the largest in the NOAA/GOES 
                         records, classified as an X28 flare, and the Oct 28 flare was the 
                         fourth most intense X17. The objective of this study is to analyze 
                         the phenomena of Solar X-ray flares during the period from October 
                         to November 2003 in order to use the Soft X-ray Sensors (XRS), 
                         onboard the Geostationary Operational Environment Satellites 
                         (GOES), operated by NOAA, since 1974. The XRS is a whole-disc 
                         X-ray photometer that measures in real-time the solar X-ray flux 
                         in the spectral range of 0.5 to 4.0A (short Sun channel) and 1 to 
                         8A (long sun channel). This X-ray data can be obtained through the 
                         database of NOAA/SEC. To investigate the XRS data in the period of 
                         the Halloween events, were determined 35 flares of the classes M 
                         (1x10\−5) and X (1x10\−4) in the 0.5-8.0A wavelength 
                         from GOES10 and GOES12. This study consisted of determining the 
                         beginning and end of the flare, so then we can determine the 
                         intensity, integrated energy and the time duration of these solar 
                         flares. To compare this study with the actual effects, we also 
                         analyze images of the sun in the Extreme Ultra Violet (EUV) 
                         obtained from the Extreme ultraviolet Imaging Telescope (EIT), 
                         onboard the Solar and Heliospheric Observatory (SOHO). Some of the 
                         effects on earth upper atmosphere/ionosphere of these flares are 
                         also discussed.",
