An enormous explosion on the surface of the Sun blasted an array of solar particles Earth’s way and the storm will hit tomorrow.
Scientists have warned the storm could wipe out satellites, GPS navigation systems and mobile phone signals.
The solar storm will hit the northern hemisphere, which could lead to the Northern Lights, or aurora borealis, being seen as far south as the upper reaches of Scotland.
The US National Oceanic and Atmospheric Administration (NOAA), who spotted the solar storm using two NASA satellites, said: “A minor geomagnetic storm watch is now in effect for the 14 and 15 March, 2018. Aurora may be visible at high latitudes.”
