📌Aurora Borealis
The fascinating heavenly scene of Aurora Borealis is best seen from Lapland. In the city of Rovaniemi, the city of Santa Claus, the Arctic Center is located, which records and studies this interesting light phenomenon. Green lines of polar light could be seen over the past couple of nights above this Finnish city. The latest data show that the polar light in the north of Finland appears every other evening, and can only be seen if the sky is completely clear. Light is studied and recorded by digital cameras and images from the satellite. Aurora Borealis occurs when particles of electricity from the Sun collide with the Earth's atmosphere, and can be seen over the entire Arctic, in the north of Norway and Finland, above Siberia and parts of Alaska and Canada.
