Radio waves at the 1–30 MHz range are known as high frequency (HF) radio waves. HF radio waves are often used by commercial airlines, ham radio operators, and various industries. These waves can be disrupted by different kinds of solar weather, including solar flares. During a solar flare, the sun sends X-ray photons into Earth’s ionosphere. The ionosphere reflects and modifies HF waves. When the ionosphere has an increased number of photons, there can be a radio blackout on the dayside part of Earth. These radio blackouts can cause broadcast television sound, public service radio, cell phones, and navigation systems to fail.
