One of the reasons tourists visit Iceland is because of the world renown northern lights. However, it is also one of the most elusive and unpredictable attractions the country has. It was revealed that a lot of things or variables need to be considered to see them, i.e. season, weather, length of stay, location and luck.

Others can say that the city of Reykjavik, Iceland's capital, is indeed privileged and fortunate when the Northern lights chose to appear above it. To witness the world famous Northern Lights spectacle in all its glory, residents and visitors turned off their street and home lighting for one hour to improve visibility.

CNN shared that the city council was the one who ordered most neighborhoods to shut down city lights on Wednesday night for the unforgettable opportunity to view the dancing lights of the Aurora Borealis.

Residents gladly obliged to turn off the lights in their homes to help reduce light pollution in the city. Also, the council reminded motorists to take care while driving.

WHNT notes how people took to social media to share the photos and videos of the natural phenomenon, with skies tinted green, blue and purple. The unique colors of the Northern Lights are made by the Earth's spectra of gases and the height in the atmosphere where the collision of particles from the sun and the Earth's gases takes place.

However, Iceland is not the only place where the illuminations appeared. Certain areas in the United Kingdom also caught a glimpse of the dazzling skies. It was also visible in Northumberland in northeast England, specifically over the Bamburgh lighthouse at stag Rock.

A photo of the lights in Northern Ireland posted by photographer Stephen Wallace circulated and created a buzz on Twitter.

It was reported that the best time in Iceland to see the Northern Lights or Aurora Borealis, triggered by solar particles entering the Earth's atmosphere, is from October to March.
