                         (HILDCAA) intervals are capable of causing a global disturbance in 
                         the terrestrial ionosphere. However, the ionospheric storms' 
                         behavior due to these intervals is still not widely understood. In 
                         the current study, we seek to comprise the HILDCAA disturbance 
                         time effects in the total electron content (TEC) values with 
                         respect to the quiet days' pattern by analyzing local time and 
                         seasonal dependences, and the influences of the solar wind 
                         velocity on a sample of 10 intervals that occurred in the years 
                         2015 and 2016. The main results showed that the hourly 
                         distribution of the disturbance TEC may vary substantially between 
                         one HILDCAA interval and another. An equinoctial anomaly was found 
                         since the equinoxes represent more ionospheric TEC responses than 
                         the solstices. Regarding the solar wind velocities, although 
                         HILDCAA intervals are associated with highspeed streams, this 
                         association does not present a direct relation to TEC disturbance 
                         magnitudes at low and equatorial latitudes.",
