NASA facts - Solar storm

The Solar Dynamics Observatory (SDO) will provide a new eye on the sun that will deliver solar images with 10 times better resolution than high-definition television. This mission will zoom in on the cause of severe space weather—solar activity such as sunspots, solar flares, and coronal mass ejections. Space weather can pose a threat to astronauts as well as to aircraft crews flying over Earth’s northern and southern polar regions—and that’s just the tip of the iceberg. Satellite communications, navigation systems, and electrical power to our homes can all be disrupted by magnetic storms triggered by solar activity...sunspots, solar flares, and coronal mass ejections.
