We are a group of people fascinated by a natural occurrence, which is one of the astronomical phenomena called ‘The Northern Lights’ also known as ‘The Aurora Borealis’. We came up with an idea of creating a website and putting together our knowledge, so as to make it an easy task for people to be informed about the northern lights and also to have a better view of the Aurora Borealis. This website has its own distinct photo database which is compiled from our visits to the Northern Lights countries. In the future, we hopefully think of showing you pictures from the Southern Lights countries. Explore the world of the Northern Lights and know more about the wonderful natural phenomenon!
How often do you see the Northern Lights?
In Troms and Finnmark, we can see the Northern Lights every other clear night, if not even more frequently. From Southern Norway, sightings would be only a few times a month while in Central Europe hardly more than a few times a year and they have even been seen from the Mediterranean but only a few times each century. To the North of the Auroral zone, on Spitzbergen, the Northern Lights are very common, although they don’t appear as often as in Norway.
What exactly are the Northern Lights?
The Northern Lights stem from when large numbers of electrically charged particles (electrons) at a high-speed stream in towards the Earth along its magnetic field and collide with the highest air particles. The air then lights up rather like what happens in a fluorescent light tube. The resulting colors reflect which gases we find up there, the most usual yellow-green color coming from oxygen. Red coloring is also due to oxygen with a contribution from nitrogen. The violet we often see at the lower edge of the aurora is due to nitrogen, as is most blue coloring. The charged particles originate from the sun, and it is the ‘weather’ conditions on the sun that decide whether or not we will see the aurora. Particles can stream out from the sun and some are captured by the Earth’s magnetic field and find their way into the polar regions. On the way, they travel out into the night side of the Earth and gain extra energy – we still lack understanding of exactly what happens out there!
