A temporary gift of solar physics that won't last forever
Across fifteen northern states this Sunday night, the sky may offer what it rarely does so far south: the aurora borealis, drawn earthward by a geomagnetic storm forecast by NOAA. The sun, currently at a 500-year peak of activity in its eleven-year cycle, has been sending more frequent eruptions into the solar wind, bending the usual boundaries of where such light can be seen. For those willing to seek darkness and elevation, the hours between 10 p.m. and 2 a.m. hold the possibility of witnessing one of nature's oldest and most humbling spectacles — not in the Arctic, but from their own northern horizon.
- A Kp index of 5 — well above the threshold for typical aurora visibility — will push the northern lights significantly south of their usual Arctic range this Sunday night.
- Fifteen states from the Pacific Northwest to New England fall within the forecast zone, creating a rare mass-viewing opportunity for millions of Americans who rarely see the aurora from home.
- Light pollution, cloud cover, and low elevation remain the primary obstacles standing between viewers and the display, demanding deliberate travel to darker, higher ground.
- The window is narrow: NOAA identifies 10 p.m. to 2 a.m. as peak viewing time, with Monday offering a secondary but diminished chance as the Kp index drops to 3.
- This event is not an anomaly but part of a sustained solar maximum — a 500-year peak in activity — meaning enhanced aurora access will continue through 2026 before fading.
Sunday night presents an uncommon opportunity for residents of the northern United States: the aurora borealis may be visible without a trip to Alaska or Canada. NOAA is forecasting a geomagnetic storm strong enough — rated Kp 5 on a scale of nine — to push the northern lights well south of their usual range, with visibility spanning fifteen states from the Pacific Northwest to New England. Monday night may offer a secondary viewing chance, though with a lower Kp index of 3, the display is expected to be less vivid.
The viewing zone is wide. Minnesota and North Dakota fall entirely within it. Montana, South Dakota, and Wisconsin are largely covered. Northern stretches of Idaho, Washington, Michigan, New York, Vermont, New Hampshire, Maine, Iowa, and Wyoming also lie within the forecast area. Alaska, as always, will see the most dramatic show — but the farther south you are, the more dependent you become on clear skies and favorable conditions.
Timing and location are everything. NOAA recommends the hours between 10 p.m. and 2 a.m. for peak activity. Viewers should escape city light, seek higher ground, and face north with patience. Photographers will want a tripod and wide-angle lens, with camera settings tuned for low light; smartphone users can also succeed with night mode and a steady mount.
The deeper story behind this forecast is the sun itself. NASA has identified the current solar cycle as a 500-year peak in activity, with solar flares and eruptions occurring more frequently than they have in half a millennium. This heightened activity is expected to persist through 2026, making the northern lights more accessible to ordinary Americans than usual — a temporary gift of solar physics, and Sunday night is simply its latest offering.
If you live in the northern tier of the United States, Sunday night offers something rare: a chance to see the aurora borealis without traveling to Alaska or Canada. The National Oceanic and Atmospheric Administration is forecasting a geomagnetic storm strong enough to push the northern lights well south of their usual Arctic home, potentially visible across fifteen states from the Pacific Northwest to New England.
The forecast hinges on a Kp index of five—measured on a scale that tops out at nine—which NOAA says will make the aurora noticeably brighter and extend its visibility line significantly farther into the continental United States than typical. Sunday night into Monday morning represents the window of opportunity, with Monday expected to remain favorable though somewhat less dramatic, with a projected Kp index of three.
The geography of visibility is broad. All of Minnesota and North Dakota sit squarely in the viewing zone. Nearly the entire states of Montana, South Dakota, and Wisconsin fall within the forecast area. Northern portions of Idaho, Washington, Michigan, New York, Vermont, New Hampshire, Maine, Iowa, and Wyoming also lie above the projected view line, meaning the lights could appear under the right conditions. Alaska will see the strongest display. The farther north you are, the better your odds; the farther south, the more dependent you become on clear skies and favorable atmospheric conditions.
Timing matters. NOAA recommends watching between 10 p.m. and 2 a.m., when the aurora tends to be most active. Location matters equally. You'll need to get away from city lights—the glow from towns and streetlamps will wash out the display. Higher elevation helps; a hilltop beats a valley floor. Point yourself north and wait. Patience is part of the experience.
For those wanting to capture the lights on camera, a tripod and a wide-angle lens are essential. The camera needs to be stable and the settings adjusted for low light—an aperture of four or tighter, or an F-stop of 4.0 or lower. Even smartphone photographers can succeed, though they too should use a tripod, disable the flash, and engage night mode if their device offers it. The goal is to let the camera gather as much light as possible without introducing blur or artificial illumination.
What makes this forecast noteworthy is the broader context. The sun is currently in what NASA has called a 500-year peak of activity in its eleven-year cycle. Solar flares and other eruptions are more frequent now than they have been in half a millennium, and this heightened activity is expected to persist through 2025 and into 2026. That means the northern lights have become more accessible to ordinary Americans than they typically are—a temporary gift of solar physics that won't last forever. Sunday and Monday nights are simply the next opportunity to witness it.
Notable Quotes
The aurora borealis will become brighter than usual as it moves away from the poles and could be quite pleasing to look at— NOAA forecast
The Hearth Conversation Another angle on the story
Why does the sun's activity matter so much for seeing the lights from the lower forty-eight?
The aurora happens when charged particles from the sun collide with Earth's atmosphere. During a solar maximum, there are simply more of those particles being ejected. More particles means the glow extends farther from the poles.
So this 500-year peak—that's genuinely rare?
Yes. We're in an unusually active period that won't repeat for centuries. It's why people in places like Iowa and Wyoming have a real shot at seeing something they might never see again.
What's the actual difference between a Kp index of five and a Kp index of three?
Five means the lights get brighter and push farther south. Three is still good, but more subtle. You need darker skies and clearer conditions to see it.
Why does altitude matter so much?
You're trying to see above the atmospheric haze and light pollution. A hilltop gives you both elevation and distance from city glow.
If someone's in, say, southern Minnesota, what are their real odds?
If they drive north, away from the Twin Cities, and the sky is clear, they have a genuine chance. If they stay in town, they probably won't see much.
And after this weekend, when's the next good opportunity?
Monday night is still favorable. After that, it depends on the sun. There will be other storms, but we're in a window of heightened activity that lasts through 2026.
