Sun unleashes 'X-Class' solar flare

Help

The Sun has unleashed its most powerful eruption of 2013 so far.

The solar flare - a sudden release of radiation - peaked at 1705 BST on Monday, and was associated with a huge eruption of matter.

When these eruptions reach Earth, they can interfere with electronic systems in satellites and those on the ground.
