see this light, you need a clear weather, be between the 21 September to 21
march approximately, and be lucky, because even if there are all good
conditions it’s not sure to see it. The northern light is really beautiful
natural effect. There are a lot of green and sometime purple lights present in
the sky. To see that, we were going to a special place, an ice lake, with the
clear view. We were lucky because we just saw one little light and when we
decided to go back home, we saw 2 others light and at this moment the show
began, and we were just enjoying the moment.
