GREAT EXPECTATIONS

2013
Solar flares are disrupting Earth's magnetosphere

The Sun reaches its solar maximum this year - the period of greatest activity in its 11-year solar cycle. Because of the unusually low level of activity in recent years, this has caused a sudden build up of energy now, with large "solar storms" hitting Earth's magnetosphere. These are strong enough to disrupt electronic systems on the ground. Satellites, air travel, car navigations, the banking system, hospital equipment, computers and many other machines are affected during this period.*
