The northern lights forecast for Friday night is giving sky-watchers across the northern United States a reason to stay up late, with the aurora borealis potentially dazzling observers in as many as 10 states. After an unusually active week along the northern border, conditions are once again lining up for a memorable display.

For those positioned in the right spot, this could be a rewarding evening under the stars — provided the weather and timing cooperate.

What the Forecast Shows

NOAA issued a Kp index of five for Friday night, a level that suggests heightened auroral activity with more motion and dynamic formations. According to the agency, this kind of reading promises a “quite pleasing” view for observers fortunate enough to be in the right location.

Adding to the optimism, NOAA is forecasting strong geomagnetic storm impacts for Friday night. These storms can fuel bolder, more vivid auroral displays, raising the odds of a striking show.

Where You Might Catch the Show

Friday’s forecast points to a “low” but real chance of spotting the northern lights across a band of northern states. The potential viewing areas include:

• Northern Washington and the northern tip of Idaho
• Montana and the Montana-Wyoming border
• North Dakota and northern South Dakota
• Northern Minnesota, northern Wisconsin, and Michigan’s Upper Peninsula

As is almost always the case, Alaska enjoys a considerably higher chance of seeing the aurora than the contiguous states.

A word of caution for weekend planners: the forecast turns less favorable by Saturday night. The Kp index is expected to drop to two, with visibility likely retreating well past the northern U.S. border. In other words, Friday is the night to make the effort.

How to See the Northern Lights

Catching the aurora is partly about timing and partly about location. The window between 10 p.m. and 2 a.m. typically offers the best viewing opportunity.

Beyond timing, your surroundings matter enormously. The lights show up far more clearly in places with little to no light pollution, so escaping city glow makes a real difference. A dark sky free of bright moonlight will dramatically improve what you can see.

How to Photograph the Northern Lights

If you’re hoping to capture the moment, a few simple adjustments to your camera or smartphone can go a long way. Recommended techniques include:

• Using wide-angle lenses to take in more of the sky
• Setting a low aperture to let in more light
• Mounting your device on a tripod for stability
• Switching on night mode if your setup supports it

One important tip: avoid using flash, which will wash out the delicate colors of the aurora rather than enhance them.

Why the Aurora Has Been So Active

This week’s frequent sightings are part of a larger astronomical story. The northern lights have been especially busy along the northern U.S. border, with Thursday offering the strongest opportunity of the week — NOAA had forecast visibility across as many as 17 states that night.

The heightened activity traces back to the sun. In 2024, the sun reached the peak of its 11-year solar cycle, generating what was described as a 500-year high in auroral activity. That surge has kept aurora displays relatively consistent across the U.S. ever since.

The window, however, won’t stay open forever. Forecasters expect northern lights showings to diminish significantly by 2027, making the current stretch a particularly good time to seek out the phenomenon.

Don’t Miss Your Chance

With a favorable Kp index, strong geomagnetic activity, and a multi-state viewing zone, Friday night represents one of the better aurora opportunities of the week. If you live in or near one of the northern states on the list, it may be worth bundling up, finding a dark patch of sky, and looking north between late evening and the early morning hours.

The aurora borealis remains one of nature’s most captivating spectacles — and with the active phase of the solar cycle gradually winding down, nights like this one are worth savoring while they last.
