The use of VLF signals to monitor the changes that occur in the ionosphere resulting from solar variability, has helped to understand how different ionospheric layers depend upon the Sun. These different ionospheric layer responses play a significant role in determining space weather impacts. Our system was created to be a permanent monitor to study the effects on the D-region of the ionosphere and explore any major impacts due to sun radiation exposure. The use of inexpensive equipment proved to be effective and the key point in the creation of this system.
