Finland: Aurora Borealis in Lapland

Today I got six postcards: one from Finland, two from Brazil, my first card from Iraq, one from Germany and one from France.

The card from Finland shows Aurora Borealis in Lapland. The Aurora Borealis is caused by the collision of solar wind and magnetospheric charged particles with the high altitude atmosphere and can be seen in the high latitude regions in Antarctica and Arctica.
