 High Frequency Radio propagation is dependent on Solar Weather. Ultraviolet radiation from the sun creates and maintains the ionosphere.

Solar flares, coronal mass ejections and coronal holes, also from the sun can deteriorate or disrupt HF propagation.    This presentation will introduce the positive and negative effects of solar weather  on HF
propagation, and how the radio amateur can detect and compensate for these effects and maintain HF communications.
