Tag card #47 - Wishlist tag from Finland
I always wanted to see Northern lights! Here they are! Northern lights caused when charged particles from Sun collide with atoms and molecules in the Earth's atmosphere at the altitude of 90-250 km. Due to collision oxygen and nitrogen are emitting auroral light.
Huge thanks to Sirpa for this interesting card, and for the cute dog stamp!
