Last night’s bump in auroral activity took a long time to develop into a nice display. A funky green arc low in the northern sky glowed meditatively for hours. Not until 1 a.m. did it stir. A few faint but lofty rays grew from the band and reached up toward the North Star. These faded, reappeared and finally regrouped to create a beautiful crown-like rayed arc.
The lights cooked all night as the fireflies zipped and flashed about. What a wonderful coincidence that firefly green neatly matches the aurora’s tint. Last night’s minor storm was visible across the upper Midwest in places like Minnesota, Wisconsin and Michigan. There’s a small chance for minor storms again tonight. As of 6 p.m. CDT this evening, activity is up a little and the direction of the solar wind is still south, favorable for auroras. Be on the lookout.
