Fears of disruption as big solar storm strikes the Earth
The Earth is currently being battered by a storm of charged particles from the Sun, which could disrupt power grids, satellite navigation and plane routes.
The storm, the largest in five years, will bombard the Earth's magnetic field throughout Thursday.
It was triggered by a pair of solar flares - the largest of their kind - earlier this week.
