(AP) -- The Northern Lights have lit up the skies above Scotland, northern England and northern parts of Ireland after the biggest solar storm in more than six years bombarded Earth with radiation.
The Canadian Space Agency posted a geomagnetic storm warning on Tuesday after residents were also treated to a spectacular show in the night sky.
Ken Kennedy, director of the Aurora section of the British Astronomical Association, said that the lights, also known as the aurora borealis, may be visible for a few more days.
The Northern Lights are sometimes seen from northern parts of Scotland but the unusual solar activity this week means the lights have also been visible from northeast England and Ireland, a rarity.
Geomagnetic storms cause awesome sights, but they can also bring trouble.
According to the National Oceanic and Atmospheric Administration, problems can include current surges in power lines, and interference in the broadcast of radio, TV and telephone signals.
