Reacts to ultraviolet, X-ray, gamma-ray and other types of cosmic rays. Propagation depends on the lower regions of the ionosphere called E- and D-Layer. These are in fact not sharp bordered layers. Night time radio propagation happens via the ionosphere at heights above 100 km. During the day solar radiaton generates the D-Region.

You are on the Sudden Ionospheric Disturbances Monitoring Station A118. The solar flares release energy that affect the near Earth environment and particularly a part of the atmosphere called ionosphere. Through monitoring of the propagation of radio communication signals, this station aims at detecting some of the ionospheric effects resulting from solar flares. Those effects are known as Sudden Ionospheric Disturbances. This website gives you access to real time measurements.
