I have been chasing for good photo of aurora borealis in my home during some years already.
It is not very common to see aurora well at a latitude of 57.9° N, but it's still possible - if you follow the forecasts and weather, or if you are just very lucky :).
Finally on 7th of October this year I was in right place at right time with mu camera and clouds went away for just this right hour...
Therefore I chose this photo as my favorite in 2015.
