                         ionospheric F-region response due to moderated geomagnetic storm 
                         which took place during 22-23 July, 2009. During the period 
                         studied the geomagnetic Dst index reached minimum value of -79 nT 
                         at 1000 UT on 22 July and Kp index reached 6-. This investigation 
                         is carried out using a chain of 15 GPS stations and another chain 
                         of 3 digital ionosondes stations. Both chains are located in the 
                         South American sector and the instruments cover from low-latitudes 
                         to equatorial region. The total electron content (TEC) recorded 
                         during the disturbed period presented both positive and negative 
                         storm phases. Also, the ionospheric sounding data showed presence 
                         of traveling ionospheric disturbances (TIDs) during the recovery 
                         phase. The present geomagnetic storm is very interesting because 
                         it took place during atypical low solar activity (LSA) period, 
                         this low solar cycle was one of longest and presented very high 
                         number spotless solar days.",
