Living With a Star Current Space Weather Links Return to LWS DE Home
The current weather in space (see the overview and forecasts) starts at the Sun, which is the source of Coronal Mass Ejections and flares, both associated with solar active regions. These produce changes in the solar wind that flows by the Earth and the other planets. The earth’s magnetosphere responds to upstream conditions with changes in the magnetopause, energetic particles in the radiation belts, auroral displays, and currents and changes in the ionosphere and magnetic field. One fairly direct effect of space weather is on radio broadcasts.
