Two years ago at this time, I was in northern Norway hunting the Aurora Borealis.
Standing at night outside in the cold looking in the starry sky. Admiring the countless bright spots on the dark surface. Than, slowly but sometimes all of a sudden, like someone has switched it on, it appears: the Aurora.
Bright, mostly green, light dances in front of the stars. It turns the scene in a mysterious ambience. Even the white snow turns greenish. What an experience. Sometimes it lasts only for a couple of quarters of an hour, sometimes it lasts nearly the whole night.
Sometimes it feels, like a painter has painted an abstract piece of art on the dark surface, while sometimes the changing rate of the light structures is enormously hight and builds new structures every few seconds. Sometimes it looks like the painting of light stands still in one place, and sometimes it moves rashly over the sky. Sometimes it looks like curtains and the next time you can see columns. Amazing!
