Beautiful pictures, Kamikaze! Thanks a lot, I always check the Northern Lights pictures at
www.spaceweather.com the site where the activity of the Sun is displayed. And to add a bit on the philosophical side: The funny thing about spirals, in the sky, on the ground, the way water is moving when disappearing in a hole, the whirlwind moving in a spiral, galaxies forming, DNA chains, they all show a symbol of eternal movement, there's no finite point in space or time, isn't that great? That's one of nature's laws.
