FI-1681852



Unusually, but I don't have many cards from Finland, so this official that I got from Anne is a nice addition indeed. And one more northern light card! The back of the postcard explains why there are northern lights at all... "Caused when charged particles from Sun collide with atoms and molecules in the Earth's atmosphere at the altitude of 90-250km. Due to the collission oxygen and nitrogen are emitting auroral light."
