I become addicted to the Northern Lights since I've seen them the first time in my life in Porjus, Sweden 2013. Undoubtedly it's the most beautiful thing I've seen in my life. It kinda makes you shocked and speechless. You can never get enough of watching the beauty of the Lights. Despite the fact that outside is dark or frozen, you'll simply become numb to any other senses and troubles around yourself and you'll completely feel isolated and happy. It's an unfortunate that it can't be seen any time we want or anywhere we want.
I was lucky to see the Northern Lights (also known as "Aurora Borealis" or southern version "Aurora Australis") third year in a row. First Porjus and Kiruna, Sweden in 2013, secondly Skaftafell and Blue Lagoon, Iceland in 2014 and lastly Lyngen, Norway in 2015 and Alta, Norway in 2016. Below you can watch a 2 minutes long photo lapse of my photographs.
