↑ What causes geomagnetic storms?

By Doron Tal, 4X4XM

Solar magnetic storms induce geomagnetic storms. The sun's magnetic field undergoes a periodic reversal, flipping its polarity in an approximately 11-year cycle. This process is associated with various solar phenomena, such as sunspots, flares, and coronal mass ejections (CME).

The project "Understanding HF Propagation" provides a detailed overview and tutorials on HF propagation.
