Abstract: In its latest findings, NASA has come up with a prediction of a massive solar storm (flare) that can hit earth anytime in 2012-13. Right from GPS systems, credit card transactions, mobile phone services, communication services, radio and air travel to smart power grids and electrical transformers, all are vulnerable to the solar storm. The damage can be controlled by putting satellites in safe mode. The power grids can be saved by disconnecting them from the supply and transformers. This will require an accurate forecasting about the coming solar storm. This project is designed to monitor solar flares on Earth by tracking changes in Very Low Frequency (VLF) radio transmissions as they bounce off Earth’s ionosphere. The strength of the received signal changes according to the extent of ionization in the ionosphere. Thus, by monitoring the amplitude of VLF signals, the appearance of solar flares can be detected.
