It led to some spectacular images caught on camera
Over the night, the unique phenomenon, also known as the Aurora Borealis, appeared in many different locations around the country.
The Northern Lights are the result of electrically-charged particles from the sun that enter the earth's atmosphere. They can be seen in the skies above the magnetic poles of the northern and southern hemispheres.
The best spots to catch a glimpse of them are areas where there are very low light pollution, usually in the north of the country.
