Unusual Aurora Borealis Displayed Across the U.S.
On a remarkable Tuesday night, the skies over Monroe, Wisconsin, and many other parts of the United States were illuminated by the stunning hues of the aurora borealis. This rare sight extended as far south as Florida and Alabama, a testament to the intensity of the geomagnetic storms that had swept across the country.

States such as Idaho, Iowa, and Missouri, among others, witnessed this captivating phenomenon. Even regions unaccustomed to such sights, like parts of Florida and Alabama, experienced the northern lights.
“Well, we had activity tonight — a lot of geomagnetic storm activity,” remarked Shawn Dahl, from the NOAA’s Space Weather Prediction Center, in a video on X.

These geomagnetic storms arise when charged solar particles interact with Earth’s magnetic field, not only creating spectacular light displays but potentially disrupting technology like satellites and power grids. The current displays were triggered by coronal mass ejections (CMEs) from the sun, which reached Earth on Tuesday.
The geomagnetic storm reached G4 levels, as per the NOAA’s classification, making it particularly intense. “It was traveling significantly faster than these other two, and we think that’s going to pack even a stronger punch than what we’ve already experienced,” Dahl explained. A third CME is expected to hit Earth midday Wednesday.

The aurora might be visible across much of the northern U.S., possibly reaching as far south as Alabama and northern California, according to the Space Weather Prediction Center. The U.K.’s Met Office forecasts visibility over Britain, though cloud cover may obscure the view.
How to see (and photograph!) the northern lights
To catch a glimpse of the aurora, head to a dark location, away from light pollution. Optimal viewing times are between 10 p.m. and 2 a.m. local time, as advised by NOAA.
Consider using services like Aurorasaurus or mobile apps such as My Aurora Forecast & Alerts to increase your chances of witnessing this celestial event. For capturing the moment, use your smartphone’s night mode or adjust exposure settings manually for the best photographs.

Why we are seeing more northern lights
Increased aurora activity in the U.S. is due to the sun nearing its 11-year solar maximum, leading to more solar eruptions. These eruptions release charged particles, which interact with Earth’s atmosphere, creating the spectacular auroras. With the sun’s activity at its peak, areas beyond the Arctic Circle, like the Midwest, are now witnessing these luminous displays.
