Duluth, Minnesota – Skies across the northern United States are primed for a dazzling display tonight as a moderate G2 geomagnetic storm pushes the aurora borealis into view from Maine to Oregon, offering millions a rare opportunity to witness northern lights well beyond their usual range.
According to NOAA’s Space Weather Prediction Center, a surge in solar wind and magnetic activity is expected to light up skies across the Upper Midwest, Great Lakes, and far northern Rockies beginning Friday evening and lasting through early Saturday.
Residents in cities such as Duluth, Green Bay, Minneapolis, Traverse City, Grand Forks, Spokane, and Portland, Oregon, could catch glimpses of shimmering green and purple waves, especially after sunset. The most vivid displays are likely north of I-94, but clear, dark skies could allow aurora viewing as far south as northern Iowa and central Nebraska. The G2 warning also means high-latitude power grids may see minor voltage alarms, and HF radio users could experience fading signals overnight.
To maximize your chances, step away from city lights and face north—use apps or local astronomy groups for updates. Prepare for chilly evening temps and bring a tripod for photos. The geomagnetic storm warning remains in effect through early Saturday, with additional alerts possible if conditions intensify.
