Abstract :

The ionosphere is rather changeable, especially during disturbed periods and is considered an important object of experimental exploration. The ionospheric electron content observation provides data on position and structure of ionospheric regions. Nighttime enhancement in ionospheric electron content (IEC) has been studied by various researchers in the mid–latitude regions. Ionosonde data of ITEC for nighttime enhancement at mid–latitude is consider in the present study from two conjugate station Athance (38�N–24�E) and Grahmstorm(33�S–27�E) during low solar activity from January 2009 to December 2013. The events were taken as in terms of their duration, their time of occurrence of peak and their dependence on local time. Most of the nighttime enhancement events in ionospheric electron content are observed in equinox season during pre–midnight hours at Northern hemisphere with maximum between 2100–2200 hours (LT) and southern Hemisphere during pre–midnight hours with maximum between 2200–2300 hours(LT). The duration of enhancement is often large in Northern as compared to Southern.
