A geomagnetic storm warning has been issued by the The US Space Weather Prediction Centre after 17 flares burst from the same location on the surface of the Sun - creating a 'Cannibal Coronal Mass Ejection'. G3 is a 'strong' storm on the scale which ranges from 1 - minor - to 5 - extreme.
The storm could impact technology and could also mean the Aurora Borealis - the Northern Lights - being visible across much or all of the UK. Normally the lights would only commonly be visible in the north of Scotland, but could now stretch across much of the country.
John Keen of AuroraWatchUk said: "Things are going to get very interesting on the night of March 31. There were 17 flares from a sunspot group 4 at M class. We are looking at G2 magnetic storms possibly G3 if the CME impacts combine. This might bring UK-wide Auroras. "
