solar flare
Magnetic sunspot discharge
A solar flare is a sudden, intense burst of radiation from the sun's surface, typically associated with sunspots and magnetic disturbances.
These eruptions release enormous amounts of energy across the electromagnetic spectrum and can affect Earth's atmosphere, disrupting radio communications, satellite operations, and power grids.
Major solar flares sometimes trigger geomagnetic storms that produce spectacular auroras visible at unusually low latitudes.
Scientists monitor solar flare activity to predict potential impacts on telecommunications.
