Iceland's capital city of Reykjavik switched off their street lights for an hour on Wednesday (Sept 28) to give residents and visitors an unforgettable view of the Aurora Borealis.

The city council ordered street lights to be turned off for an hour in the city centre and most neighbourhoods at 10pm local time, in order to cut down on light pollution and provide people with a better opportunity to view the spectacle.

The city has been lit up with a dazzling display of the Northern Lights in recent days due to a geomagnetic storm hitting the Earth.

The aurora phenomenon is caused when molecules in the Earth's atmosphere interact with charged particles that are released from the Sun, this causes the molecules to get "excited" and they give off light as they calm down.

Aurora season has recently started as the country approaches the end of summer, resulting in darker nights. The best time to view the Northern Lights is generally between September and mid-April.

But it was not just Iceland that got to witness nature's light show, the solar storm was so strong that even countries like Ireland, Britain and certain states in the United States caught a glimpse of the mesmerising skies.

Naturally, people took to social media to share their stunning images.
