From the American Physical Society News from the 2014 APS Division of Plasma Physics Meeting
Each second, the sun hurls millions of tons of hot, charged plasma gas into space. This volatile “solar wind” buffets the magnetosphere, the magnetic field that surrounds the Earth, and can whip up geomagnetic storms that disrupt cell phone service, damage satellites and blackout power grids. Precise predictions of such outbursts could prompt measures to cope with them, just as forecasts here on Earth warn of approaching hurricanes and thunderstorms.
