                         (HILDCAA) intervals are capable of causing a global disturbance in 
                         the terrestrial ionosphere. However, the ionospheric storms 
                         behavior due to these geomagnetic activity forms is still not 
                         widely understood. In this study, we seek to comprise the HILDCAAs 
                         disturbance time effects in the Total Electron Content (TEC) 
                         values with respect to the quiet days' pattern analyzing local 
                         time and seasonal dependences, and the influences of the solar 
                         wind velocity to a sample of ten intervals occurred in 2015 and 
                         2016 years. The main results showed that the hourly distribution 
                         of the disturbance TEC may vary substantially between one interval 
                         and another. Doing a comparative to geomagnetic storms, while the 
                         positive ionospheric storms are more pronounced in the winter, 
                         this season presents less geoeffectiveness or almost none to 
                         HILDCAA intervals. It was find an equinoctial anomaly, since the 
                         equinoxes represent more ionospheric TEC responses during HILDCAA 
                         intervals than the solstices. Regarding to the solar wind 
                         velocities, although HILDCAA intervals are associated to High 
                         Speed Streams, this association does not present a direct relation 
                         regards to TEC disturbances in low and equatorial latitudes.",
