Tonight, a stunning cosmic event may take place across parts of the United States. As the Space Weather Prediction Center (SWPC) warns of unsettled geomagnetic activity, the northern lights could be visible as far south as Michigan, Maine, and even New Hampshire. This unexpected spectacle is linked to a coronal mass ejection (CME) from a C5.5 solar flare that occurred on June 17. This release, paired with fast-moving solar wind from an Earth-facing coronal hole, is expected to cause minor geomagnetic storm conditions, with the best chance for aurora viewing between 2 a.m. and 5 a.m. EDT (0600–0900 GMT) on June 20. If you’re in the right location, tonight might just be your chance to witness nature’s spectacular light show.
Nine US States Could Experience the Northern Lights Tonight
Here is a list of the nine states where the northern lights are most likely to be visible tonight, according to the latest NOAA forecast. These states are ordered based on their proximity to the auroral oval, with Alaska having the highest likelihood of aurora sightings, followed by other northern-tier states. Keep in mind that the intensity of geomagnetic storms can sometimes surprise observers, so even states near the aurora visibility line might get an unexpected view of the lights.
- Alaska – As the state closest to the auroral oval, Alaska has the highest probability of seeing spectacular auroras. Anchorage, Fairbanks, and other parts of Alaska should prepare for a stunning display tonight.
- Montana – As a northern state, Montana is expected to see visible auroras, especially in the later hours of the night.
- North Dakota – With a relatively close proximity to the auroral oval, North Dakota could see auroras on the horizon.
- Minnesota – Minnesota’s northern regions are in the forecasted aurora visibility zone. Residents in areas like Duluth could catch the light show.
- Wisconsin – Wisconsin, especially northern parts such as Ashland, may experience auroras.
- Michigan – The Upper Peninsula of Michigan is the most likely location to witness the northern lights in this state. The auroras may be visible to the north and east.
- Maine – Maine is another state where aurora watchers should keep their eyes on the skies. A visible display is expected, particularly in northern regions.
- Vermont – Vermont is on the edge of the aurora visibility zone, so residents here may see the northern lights if the storm intensifies.
- New Hampshire – Similar to Vermont, New Hampshire may have some chance to catch a glimpse of the auroras tonight.
How to Maximize Your Aurora Viewing Experience
For those lucky enough to be in one of the nine states forecasted to see the auroras tonight, the key to success lies in finding the perfect viewing spot. First and foremost, you’ll want to head to a north-facing location that’s far away from light pollution. Urban areas often hinder aurora visibility, so getting to the countryside, or even a nearby hill or mountain, will improve your chances. The best time to look for the northern lights is between 1 a.m. and 2 a.m. local time, as this is when the sky will be darkest and the aurora’s intensity will peak. With summer nights being shorter, the time window for observing auroras can be tight, so be prepared to stay up late.
