Minneapolis, MN – Skies across the northern U.S. could glow with aurora activity late Tuesday into early Wednesday as a moderate geomagnetic storm moves in from a solar coronal hole.
According to NOAA’s Space Weather Prediction Center, a G2-level storm watch is in effect for June 25 due to high-speed solar winds from a negative polarity coronal hole. The stream is expected to trigger minor to moderate geomagnetic activity, with effects starting Tuesday evening and continuing through Wednesday.
The best viewing potential for the aurora borealis will be in northern and upper Midwest states — including Minnesota, Wisconsin, Michigan, and extending east to New York and west into parts of Idaho and Montana. Clear skies and low light pollution will be key for those hoping to catch a glimpse.
While the event is not expected to cause major technological disruptions, minor satellite drag and possible power grid fluctuations at high latitudes may occur. NOAA recommends monitoring aurora visibility maps and staying informed via the Space Weather Prediction Center website.
The current watch remains active through June 26, with additional alerts possible if solar wind speeds intensify.
