                         sounder under the magnetic equator in the Brazilian sector. 
                         Sporadic layers appear in the equatorial region (Esq) at heights 
                         between 90 and 130 km, mainly due to irregularities in the 
                         equatorial electrojet current. However, during the recovery phase 
                         of the October 2003 superstorm, an anomalous intensification of 
                         the ionospheric density that exceeded the normal ambient 
                         background values for local time and location was observed. The 
                         parameter fbEs rose to almost 7.5 MHz during this event, due to a 
                         type c blanketing sporadic layer (Esc), which is driven by wind 
                         shear. This result is discussed in terms of the atmosphere 
                         dynamics based on magnetic signature of the equatorial electrojet 
                         current using magnetometer data. Also, using data measured by 
                         sensors onboard the Geostationary Operational Environmental 
                         Satellite (GOES) 10 we analyze the possible influence of the solar 
                         flare-associated X-ray flux as an additional source of 
                         ionization.",
