An unusual solar storm has pulled the colourful northern lights south, treating sky watchers in the US to a rare and beautiful sight.
Space weather scientist Joe Kunches told the LA Times that when charged particles that are released by the sun hit the earth (known as coronal mass ejection), it disturbs the magnetic field and causes the lights to be seen further south.
The aurora borealis was seen or photographed in more than half of all US states, including New Mexico, Tennessee, Missouri and Virginia.
The lights are normally only visible in places further north, such as Canada and Alaska.
