Solar Flare Index

The Solar Flare Index measures the intensity and frequency of solar flares, which are sudden releases of energy from the Sun’s surface. These flares emit powerful radiation across the electromagnetic spectrum, influencing space weather and potentially affecting satellite operations, radio communications, and power systems on Earth. The index quantifies flare activity by considering both the size and number of flares occurring over a certain period. A higher Solar Flare Index indicates more energetic and frequent flares, signaling increased solar activity that can have various technological and atmospheric impacts on Earth.
