NOAA Space Weather Scale

The NOAA Space Weather Scale is a classification system that measures the intensity of solar activity affecting Earth, such as solar flares and geomagnetic storms. It ranges from G1 (minor disturbances) to G5 (extreme activity). Higher levels can disrupt satellite operations, GPS, radio communications, and power grids. The scale helps forecast and prepare for space weather events, which can impact technology and infrastructure. It provides a practical way to communicate risks associated with solar and space phenomena, allowing authorities and industries to take appropriate precautions.
