Welcome

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, or SIDs.

This station is an amateur observatory located in France. Operational since early 2006, it has received the AAVSO observer code A118 in July 2006 and provides data to a coordinated network of observers around the world.

This website gives you access to real time measurements collected by the station and to a database of SID events observed so far.

I have also include general and basic information related to ionosphere, and to Sudden Ionospheric Disturbances and their detection principle.

This website aims also at providing information for building your own station. The construction of the various parts is described: the VLF antenna, the VLF receiver and the data acquisition and processing software.

I hope you will enjoy this site. Comments and suggestions are more than welcome, so do not hesitate!
