What causes northern lights and how to see them? Tips for aurora hunting in Rovaniemi


There are roughly two main reasons for people to visit Rovaniemi in darker period of the year: 1) Santa Claus and the spirit of Christmas and 2) the northern lights (aurora borealis). Santa you can see every day of the year, northern ligths are little bit trickier. What are these magical and mysterious lights and how you can experience them in Rovaniemi?

The northern lights are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of both northern and southern hemispheres about 100-200 kilometers above the surface of the Earth.

Lights appear in many colours although pale green and light red are the most common ones. Forms of the ligths can vary from scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky.

When and where to catch them?

You could think that the closer the pole you are the better are your chances to see the northern lights. There are though couple of other basic rules to remember when planning your aurora hunting trip. To begin with, you need a dark sky. During the winter season (from November to March) the daylight conditions in Lapland and Rovaniemi are quite ideal. During spring and summer time (from April until August) the night is very short or there are no dark hours at all. Best aurora months are also the colder ones.

Secondly, you need a clear sky. In the northen part of Lapland (for e.g. Kilpisjärvi or Utsjoki) auroras appear almost 75 per cent of the nights, but you won’t see them if the sky is covered with clouds or mist. Some areas ”collect” more clouds than others and some months are more cloudy than others. In Finland November is the most challenging month of winter period when it comes to clear skyes. Then again there has been excellent aurora nights also in early winter, and the weather conditions can change quite rapidly from cloudy to half cloudy or even clear.

The most ideal place to see northern lights is open and far away from artificial lighting (a field, a frozen lake). Sometimes northern lights are very pale, and it helps if you let your eyes get used to the darkness for a while. Stronger auroras you can observe also in the middle of the city center, especially if you are not right under or  next to a light source.

Always remember to dress warmly, even if there were no minus celsius degrees. If you take part in an aurora safari trip, the organizing company usually offers you all the supplies you need, including the warm outdoor clothing.

1. Take part in organized aurora tours. Local safari companies are experts when it comes to hunting auroras, and even if you are not lucky this time, the experience will be rememorable. There are several ways to experience the dark night and aurora hunt in a safari: with snowmobile, dog sledge, snow shoes or just by walking in the wilderness. Check at least these companies: Lapland Safaris, Lapland Welcome, Safartica and Santa’s Adventure. More complete list you can find from www.visitrovaniemi.fi.

2. Spend a night in a glass igloo. Arctic SnowHotel in the outskirts of Rovaniemi offers the most cosiest way to experience auroras from the comfort of your own bed. The hotel has also a Aurora Alarm service so you won’t miss the show. More details: www.arcticsnowhotel.fi.

3. Combine sauna and auroras. To ensure the best location for your aurora hunt you need an open and dark area. And what if there could also be a warm sauna just next to your viewing place? Finnish Sauna by the Lake offers you beautiful surroundings just 20 minutes from the city center. More details also from www.guesthouseborealis.com.

4. Aurora hunt in the city. You can also try to see the lights inside the city area. Locals suggest places like the riverbank behind Arktikum house or the top of the Ounasvaara hill. You can take your city map and ask guidance from the hostel/hotel reception: look for open areas like football or ice skating fields. Locals also recommend  top of Ounasvaara hill for watching the auroras. It is quite easy to access and there is also a restaurant if you want to combine Lappish food experience and aurora hunting.
