Strong To Severe?

A solar storm that had been rated 'strong-to-severe' delivered only a glancing blow to Earth, according to Reuters. Scientists at NOAA's Space Weather Prediction Center said the solar storm came from a monster sunspot that was so big, it could be seen from Earth with the naked eye (although it's dangerous to look directly at the sun). Solar storms can interfere with satellites, power grids and navigation systems. But scientists said while some people in extreme northern latitudes might see heightened auroras, there won't be damage this time. Sunspot activity is expected to peak in 2013. (Reuters)
