A sun pillar. Source
In the background, a beam of sunlight is clearly visible shooting up from the horizon. This effect is called a "sun pillar". As ice crystals order during their fall through the atmosphere they can bend light in all sorts of unique ways. One way they bend light is to make a pillar of sunlight like the one shown here. This effect is fairly uncommon, but very beautiful. This particular picture was taken in Östersund, Sweden.
