Aurora's like this rarely reach below 60 kilometers and this one has reached this point. This beautiful affect is caused by energetic electrons and protons striking atoms and molecules in the Earth's atmosphere. This occurred last month in Kvaloya, Tromso, and Norway. The effect creating in the middle is called the auroral corona. This corona affect only occures if the aurora is forming directly overhead, and it creates this green light show that appears to be coming straight at you. I personally have never seen one in real life, but i would imagine it would be a phenomenal experience to do so.
