Northern Lights on Chirstmas Eve (Oulu, Finland)
After living in Finland for 8 years this was the first time I saw the northern lights.
It was for a brief moment, and with lots of light pollution because I was in the city, but it was still very much worth it.
It is hard to describe how it exactly goes but like a small cloud of light moving slowly.
Hope it won't have to take more eight years to see it again.
