Superior National Forest - Cook County, MN. Last night the northern lights made a small appearance in northeast Minnesota. The forecast was calling for mild geomagnetic storms and that's exactly what we got. I made this photo at 10:02 PM just as some faint pillars were beginning to show up. The pillars were barely visible to the naked eye, but a 30 second exposure made them look more noticeable.
For the remainder of the night (well... at least until the clouds moved in around 1:30), there was a soft green glow on the northern horizon but no more pillars. It also was the first night that got rather chilly. The air temp was 19 degrees as I was sitting in this location watching the lights slowly weave their way across the northern sky.
