Solar Storms

Solar storms are magnetic storms that interfere with Earth's magnetic field, which can disrupt communication systems, power lines and other infrastructure.

The storms usually happen when the sun is an active phase of its cycle. Large solar storms usually occur about once every 100 years. The next major solar storm is predicted to occur around 2012, as the sun will be in its active phase at that time.Fox News: Powerful Solar Storm Could Shut Down U.S. for Months (January 9, 2009)

A report released by the National Academy of Sciences outlines the possible effects of a major solar storm on today's society. There has not yet been a storm as large as the one in 1859, which caused major fires on Earth. Experts in the report predict much larger problems if a similar storm would occur in today's society, due to modern technology. The report said such a storm could cut of power to 130 million people in United States, which would result in a variety of problems for households and in infrastructure.Fox News: Powerful Solar Storm Could Shut Down U.S. for Months (January 9, 2009)
