                         mostly observed at equatorial region during declining or minimum 
                         phase of the solar cycle. Their open magnetic field configuration 
                         allows the escape of particles and ions as high-speed solar wind 
                         streams. As they propagate in the interplanetary space, they form 
                         complex interactions regions which reach the geospace causing 
                         geomagnetic storms. Generally, a variety of effects are observed 
                         after the beginning of the geomagnetic storm, as it is important 
                         to understand the most important factors which impact the upper 
                         atmosphere and ionosphere. Combined events related to coronal 
                         holes and active regions in the Sun can also be observed. In this 
                         work, the ionospheric response at an equatorial region in the 
                         Brazilian sector to long duration recurrent coronal holes and 
                         their associated geomagnetic storms during the descending phase of 
                         the solar cycle 24 is investigated. For this purpose, we used 
                         instruments including GNSS receivers, ionosondes, and other 
                         ground-based systems. During the distinct Carrington, rotations 
                         are possible to observe a variety of ionospheric effects such as 
                         ionization decreases and increases, development of plasma bubbles 
                         and scintillation processes as a result of a combination of 
                         processes including prompt penetration of electric field, 
                         disturbance dynamo and the occurrence of high-intensity long 
                         duration auroral activity. This study may be useful for
