Building a Very Low Frequency Solar Flare Monitor
This instrument is a SID detector. SID stands for solar ionospheric disturbance. The project is very easy, and remarkably effective, so it is recommended that beginners start here. The success you gain will provide you a boost and encourage you to continue in this fascinating hobby. In fact there is virtually no electronic construction involved! Apart from a suitable aerial, everything is off the shelf and you probably already own it – a PC with sound card!
