                         ionospheric dynamics have been objecting to increasing interest in 
                         the last years. Notwithstanding, some key interconnections between 
                         the HILDCAA intervals impacts on the ionosphere over distinct 
                         latitudes, according to the solar cycle phase, remain to require 
                         further investigation. In this work, the F2 layer peak height and 
                         its critical frequency (hmF2 and foF2, respectively) from 
                         Digisonde data obtained over Sao Lu\ıīs (2.60 S; 44.21 W), 
                         Cachoeira Paulista (22.70 S; 44.98 W), and Port Stanley (51.60 S, 
                         57.9 W), were evaluated to unravel more details of the ionospheric 
                         responses to four HILDCAA intervals as case studies. Those are 
                         equatorial, low, and midlatitude stations, respectively, and the 
                         main results over them presented a similar trend in terms of solar 
                         cycle dependence, with the greater impact on the ionospheric 
                         density along with solar maximum conditions, despite the higher 
                         frequency of HILDCAA occurrences in the descending and minimum 
                         phases. The variation of hmF2 due to HILDCAA effects in comparison 
                         to quiet time is about 20% in equatorial and mid-latitudes, while 
                         over the low latitude station the hmF2 ranges positively up to 
                         40%. These results enhance our understanding of the HILDCAAs

                         its effects in different ionospheric latitudinal sections.",
