If you live along northern border of the U.S. and points north, there’s a 25% chance you’ll see a minor auroral storm tonight through tomorrow morning. Chances are 70% for a major storm at high latitudes across Canada and Alaska.
I suspect I’d see a glow along the northern horizon here in Duluth, Minn. right now (11 p.m.) if the sky were clear. Sadly, we’re socked in. A speedy blast of solar wind pouring from an opening in the sun’s magnetic field called a coronal hole is responsible for the enhanced activity. Take a look outside before going to bed tonight just in case.
