Northern Lights Forecast: Aurora Borealis May Be Visible In 10 States Friday Night

Northern Lights Forecast: Aurora Borealis May Be Visible In 10 States Friday Night

Skywatchers across the northern United States have reason to look up this Friday night. According to the latest aurora borealis forecast, residents in up to 10 states located near the U.S. northern border may have a chance — albeit a low one — of catching a glimpse of the iconic northern lights. While conditions are not expected to produce a dramatic, widespread display, even a faint aurora sighting is a memorable experience that draws thousands of enthusiasts outdoors each year.

Whether you are a seasoned aurora chaser or a curious first-timer, understanding the forecast, knowing the best viewing conditions, and heading to the right location can make all the difference between a breathtaking sighting and a missed opportunity.

What Is the Aurora Borealis?

The aurora borealis, commonly known as the northern lights, is a natural light display that occurs when charged particles from the sun collide with gases in Earth's atmosphere. These collisions produce vivid bursts of color — most commonly green, but also pink, purple, red, and blue — that dance across the night sky in swirling, curtain-like patterns.

The phenomenon is most frequently observed at high latitudes, particularly in countries like Norway, Iceland, Canada, and Alaska. However, during periods of elevated solar activity, the aurora's visibility zone can expand significantly southward, bringing the lights within reach of the contiguous United States. This expansion is exactly what aurora watchers are hoping to see Friday night.

Which 10 States Could See the Northern Lights Friday Night?

The states with the highest likelihood of aurora visibility on Friday night are those situated along or near the northern border of the continental United States. These states benefit from darker skies, lower light pollution in rural areas, and closer proximity to the auroral oval — the ring-shaped zone around Earth's magnetic poles where auroras are most commonly visible.

• Montana – One of the best states for aurora viewing thanks to its vast open skies and minimal urban light pollution.
• North Dakota – Flat terrain and rural landscapes give stargazers an unobstructed view of the northern horizon.
• Minnesota – The northern regions of Minnesota, including areas near the Boundary Waters, frequently produce successful aurora sightings.
• Wisconsin – Northern Wisconsin offers dark sky corridors ideal for low-level aurora activity.
• Michigan – The Upper Peninsula of Michigan is one of the most aurora-friendly locations in the Midwest.
• Maine – Maine's northern reaches and remote coastlines are well-positioned for aurora viewing on the East Coast.
• Vermont – Elevated rural areas provide good vantage points when geomagnetic activity ticks upward.
• New Hampshire – The White Mountains region can offer excellent dark skies for northern lights hunters.
• Idaho – Northern Idaho, particularly areas around Coeur d'Alene and beyond, may catch faint aurora activity.
• Washington – The northeastern corner of Washington state, away from Seattle's light dome, stands a reasonable chance.

It is important to note that forecasters are describing the probability as low, meaning residents should temper their expectations while still making the effort to check conditions throughout the evening.

How to Check the Aurora Forecast

The most reliable tool for tracking aurora activity is the NOAA Space Weather Prediction Center (SWPC), which publishes regular geomagnetic storm forecasts and aurora viewline maps. The key metric to monitor is the Kp index — a global scale that measures geomagnetic activity from 0 to 9. For most northern border states, a Kp index of 4 or higher is typically needed to produce a visible aurora. A Kp of 5 or above generally indicates a minor geomagnetic storm, which can push the aurora viewline noticeably farther south.

For Friday night specifically, forecasters recommend checking the SWPC's 30-minute aurora forecast map, which is updated frequently and provides the most current picture of where the aurora is active. Several third-party apps, including SpaceWeatherLive and My Aurora Forecast, also aggregate NOAA data and can send push notifications when aurora activity spikes in your area.

Tips for the Best Aurora Viewing Experience

Even under favorable forecast conditions, maximizing your chances of seeing the northern lights requires some preparation. Here are practical steps to improve your odds:

• Get away from city lights. Light pollution is the single biggest obstacle to aurora viewing. Drive at least 30 to 50 miles away from major urban centers and find an open field, hilltop, or lakeshore with a clear view of the northern horizon.
• Check the cloud cover forecast. Clouds are the aurora chaser's worst enemy. Even a strong geomagnetic storm will be invisible beneath an overcast sky. Use apps like Clear Outside or Windy to find the clearest skies in your region.
• Go out after midnight. Aurora activity often intensifies in the hours around magnetic midnight, which varies by location but is roughly between 11 p.m. and 2 a.m. local time.
• Give your eyes time to adjust. Allow at least 20 to 30 minutes for your eyes to dark-adapt before deciding there is nothing to see. Faint auroras can be invisible to eyes that have recently been exposed to bright light.
• Use a camera to detect faint activity. Modern smartphone cameras with night mode are remarkably sensitive to aurora light. Point your camera north on a long exposure and check the results — often a camera will detect aurora glow that the naked eye misses entirely.

Why Is Solar Activity Important for Aurora Forecasting?

The sun operates on an approximately 11-year cycle of activity, alternating between solar minimum and solar maximum. During solar maximum, the sun produces more frequent and powerful solar flares and coronal mass ejections (CMEs) — massive bursts of magnetized plasma that travel toward Earth and trigger geomagnetic storms. We are currently in Solar Cycle 25, which has proven to be more active than scientists initially predicted, leading to an uptick in strong auroral displays at lower latitudes than usual.

This heightened solar activity is one reason why aurora sightings in the continental U.S. have become more common in recent years. Events in 2024 brought some of the most widespread northern lights displays seen in decades, with auroras reported as far south as Texas, Florida, and even parts of Mexico. While Friday night's forecast is not expected to reach that level of intensity, the current solar cycle means that highly active aurora events remain a real possibility throughout 2025 and into 2026.

Final Thoughts: Don't Miss Friday Night's Aurora Window

Friday night's aurora borealis forecast is not a guarantee of a dazzling light show, but it is absolutely worth the effort to step outside if you live in one of the ten eligible states. The window for viewing may be brief, and conditions can change rapidly, so staying connected to real-time forecast tools is essential. Set your alerts, plan your viewing location in advance, dress warmly, and keep your expectations flexible.

The northern lights are one of the most awe-inspiring natural phenomena on Earth, and you never truly know when a low-probability forecast might surprise you with an unforgettable display across the sky. Clear skies and good luck to all aurora hunters heading out this Friday night.
