Last night we had a subtle display of the northern lights in northern Minnesota near Grand Marais. To my eye, they were dim and mainly shapeless, although there were a few moments when I saw rays and some dancing. Even though they were dim, it was great to see aurora!
After the display started to fade away around midnight, I decided to do a star trail image. This is a 35 minute exposure. In the center of the star circle is the north star. You can still see the pink and green glow of the northern lights on the horizon above the Cascade River.
