A long, magnetic filament burst out from the Sun after a C-class flare on Aug. 31, 2012 (NASA/SDO/AIA). We live on a planet dominated by weather. But not just the kind that comes in the form of wind, rain, and snow — we are also under the influence of space weather, generated by the incredible power of our home star a “mere” 93 million miles away. As we orbit the Sun our planet is, in effect, inside its outer atmosphere, and as such is subject to the constantly-flowing wind of charged particles and occasional outbursts of radiation and material that it releases. Although it may sound like something from science fiction, space weather is very real… and the more we rely on sensitive electronics and satellites in orbit, the more we’ll need to have accurate weather reports.
