space weather
Sun's cosmic influence
Space weather refers to conditions in space, especially near Earth, caused by solar activity—solar flares, coronal mass ejections, and solar wind.
These events can disrupt satellites, GPS systems, radio communications, and power grids.
Forecasters monitor space weather much like terrestrial weather: A space weather alert warned of possible aurora visibility and communication disruptions.
