Earth experienced beautiful auroras displays this week when solar storms hit the third planet closet to the Sun. These were experienced in Denmark, Norway, Greenland, Germany and across the northern United States and Canada. These auroras occur when the Sun erupts in a blaze known as a "coronal mass ejection" and ejects up to 10 billion tons of plasma or superheated gas off its surface. The latest aurora reached Earth in three and a half days while it covered 93 million mile.By LA News Monitor

The latest solar storm that resulted in a beautiful aurora was termed a smaller class C3 by astronomers. This doesn’t cause much harm to the planet. But, other flares or solar storm of X or M class can cause considerable damage. Astronomers say that a larger solar storm could cause havoc with electrical systems on Earth. Astronomers predict that large solar storms are more likely in 2013.
A large solar storm happened in 1859 where telegraph wires were burned across Europe and the USA. The storm named "Carrington flare", named after its discoverer, “smothered two-thirds of the Earth’s skies in a blood-red aurora a night later, and crippled all of global navigation and global communication, such as it was at that time.
Compasses span uselessly and the telegraph network went down as phantom electricity surged through the wire,” according to Dr Stuart Clark, author of The Sun Kings. In 1989, a smaller but huge storm caused the power grids in Quebec to go down for nine hours. It resulted in revenue loss of hundreds of millions' worth of dollars.
