A solar 'superstorm' is coming and we'll only get 30-minute warningSubmitted by Bob-45 on Thu, 02/07/2013 - 06:19
They cause devastation, occur every 150 years – and the last one was in 1859

A solar "superstorm" could knock out Earth's communications satellites, cause dangerous power surges in the national grid and disrupt crucial navigation aids and aircraft avionics, a major report has found.
It is inevitable that an extreme solar storm – caused by the Sun ejecting billions of tonnes of highly-energetic matter travelling at a million miles an hour – will hit the Earth at some time in the near future, but it is impossible to predict more than about 30 minutes before it actually happens, a team of engineers has warned.
Solar superstorms are estimated to occur once every 100 or 200 years, with the last one hitting the Earth in 1859.
