The Northern Lights (Aurora Borealis) is a spectacular phenomenon that occasionally lights up the dark sky in the far north. Green, blue, red, violet and many shades of these colors dance in the sky, forming shapes and pulsating like a work of art. It is pure magic to see the lights, an experience you won’t forget. There is no photograph or video that can show how impressive the real thing is. Here is a how-to-guide (with permission from the Lapland travel guidebook author) to viewing and filming the Northern Lights.
Northern lights are frequently visible north of the Arctic Circle. In Finland, Norway and Sweden, many hotels and resorts have built special places for viewers, but they are not really necessary. It is possible, but rare, to see the lights south of the Arctic Circle as well. In the far north, the lights show up regularly, and spotting them is easy if the following conditions are met.
1. Season. In summer, it is not dark enough even in the night to spot the Northern Lights. The midnight sun sheds enough light through the nigh, preventing us to view Aurora Borealis. Autumn, winter and spring are the seasons for the Northern Lights.
2. Weather. The sky must be clear, without clouds.
3. City lights. Even though there are really not large towns north of the Arctic Circle, move away from the brightest light sources if you want to see the full light show.
In northern parts of Lapland, long term statistics show that the Northern Lights phenomenon occurs in three out of four nights. If you want to increase the odds for seeing the Northern Lights, you need information on two things: the weather (for clear skies) and solar winds (when a strong burst is going to make contact with the earth’s atmosphere).
The appearance of the Northern Lights depends on the sun’s activity. The sun continuously emanates electrons and protons to the space. The flow of these electrically charged particles is known as the solar wind. The wind correlates with bursts of sunspots. When a burst causes strong enough solar winds, the particles arrive in earth’s magnetosphere in one or two days. When it happens, the particles collide with gas in the earth’s atmosphere and turn on the colorful lights for the majestic show.
Viewing the Northern Lights
Viewing the light show is simple: look at the sky. The colorful lights are easily seen by the naked eye, no instruments or aids are required. In order to maximize your viewing area, position yourself so that nothing blocks your view to the northern sky.
The lights are not harmful, since they are dancing at the height of 100 km / 62 miles and higher above the earth. Only an extremely strong solar wind may cause disturbances to sensitive magnetic and electric devices.
You don’t have to search for a particular place where seeing the Northern Lights is supposed to be guaranteed or the views are better than in another place. It doesn’t make a difference if your viewpoint is at the top of a mountain, bottom of a valley, at the yard of a rented cottage or at a car park. Especially in Lapland (Sweden, Norway and Finland), ski resorts, hotels, and activity centers like to advertise how their place is the best for viewing the Northern Lights, but in reality, only the previously listed factors matter.
There are hotels, like the Kakslauttanen Arctic Resort in Finnish Lapland that has cottages with glass roofs. Staying in a cottage like that, you don’t have to go out at all, but you can sit on the couch (in the dark) and wait for the light show to start.
Apps and alerts for Northern Lights
Nordic national meteorological institutions have public alert systems that send out email messages when the Northern Lights are anticipated to light up. Also, a number of ski resorts, like Levi and Ylläs in Finnish Lapland have their own mobile applications that alert of lights. Alert applications that can forecast the appearance of lights in all areas are available for Android and Apple mobile devices.

Photographing the Northern Lights
You can try photographing the rapidly changing lights with an ordinary compact camera or camera phone (choose the night mode), but if you want to capture decent images you need a better camera, and you have to know how to use it. You need:
- – A camera that can take good images in high ISO setting. The higher ISO value you can set, the better your chances are for capturing a sharp image.
– A lens with wide aperture. f2.8 or less is recommended.
– A tripod.
– Spare batteries if you intend to take more than a few pictures outdoors in the cold. Freezing temperatures quickly suck out life from batteries.
Tips for shooting the Northern Lights:
- – Set the largest aperture your lens allows.
– Choose the highest ISO value that still provides reasonable image quality.
– Set the focus at infinity. Do it manually. If you can’t, focus on the most distant object you can see.
– Set the exposure time to as short as possible. For instance, if the aperture is f2.8 and ISO value is 800, try exposure time between 4 and 15 seconds.
