What cause Aurora Lights? And where to see it ? :)
In this video, it would explain you how the Aurora phenomenon happen.
In other to see this phenomenon, you have to travel to those countries in far northern or southern hemisphere. These are one of those countries : Alaska (US), Canada, Iceland, Norway, Sweden, Finland :)
When? it only happens in winter time start from October (for Iceland) for Scandinavian, it would around late Xmas:) If you come to country in winter time, there is no night for you to see the Aurora :)
The sky has to be really clear, no cloudy, no windy, and not in full moon. :)
The last requirement: LUCK! That is all you need. I live in Finland for 4,5 years. I have not ever seen this phenomenon.
