Alaskans, Norwegians and Icelanders have something in common this week beside the cold. They’ve all been watching displays of the northern lights which have bloomed over Arctic latitudes night after night since late January. I know they’d be happy to share the sight with us in the lower 48, and maybe they’ll have the chance.
Auroras might reach down into the northern U.S. sometime tonight through Sunday. There is a 35% chance for a major storm in far northern latitudes and a 10% chance for minor storming in the mid-north latitudes where much of the world lives. I interpret that to mean a glowing arc pierced by a few rays low in the northern sky.
While not exactly a big blast, it’s worth keeping an eye out for that greeny glow . Since the sun’s been very quiet lately, a solar flare is not behind the uptick in activity. Rather an enhancement in the solar wind is behind the current forecast.
Joining the night scene will be the International Space Station. It returns to the evening sky for much of the U.S. and Canada starting tomorrow and continuing the next few weeks.
