Auroras come in many shapes and several colors. In the night I took this photo, there was not too much activity at first. Then patches of green started to appear a certain distance from each other, the voids in between were filled more and more until a long band crossed the sky. Near the end of it’s dance, I saw a small spiral evolving. After the moment in the photo it grew a bit in size before it lost all its structure and became a green blob.
