Aurora over Mt Noulja in Abisko National Park, Sweden

From a Swedish Tourist website:

Swedish Lapland in the far northwest corner of Sweden is a vast area of Arctic plains, forests, mountains, glaciers, lakes and rivers. It is remote, it is wild and it is adored by outdoors enthusiasts and adventure seekers for precisely those two reasons.  Because of Swedish Lapland’s proximity to the magnetic north, Swedish Lapland is a hot spot for the Northern Lights phenomenon.
The Northern Lights appear around the beginning of September to around the end of March all over Swedish Lapland. The very best chance of seeing the Northern Lights is at the Aurora Sky Station in Abisko National Park. There is no guarantee because no one can guarantee a natural phenomenon.

I received this postcard from Henrik Lundgren of Gothenburg, Sweden in February 2014..
