The aurora's reach extends farther south when the sun unleashes its fury
Twice this weekend, the sun will remind millions of Americans that they live beneath a living sky. A pair of geomagnetic storms — surges of charged particles cast outward from a star at its most active in over a decade — will carry the aurora borealis southward across the northern United States, offering a rare and fleeting invitation to look up. The phenomenon arrives not by accident but by cycle: the sun is near the peak of its 11-year rhythm, a period that will continue producing such moments through early 2026.
- A geomagnetic storm Friday night will light up skies across Washington, Idaho, Montana, and parts of the upper Midwest and Maine — regions that rarely witness the aurora with such clarity.
- Saturday brings a stronger disturbance, pushing the northern lights significantly farther south and raising the stakes for millions who may never have seen the phenomenon from their own latitude.
- The sun's current Solar Cycle 25 peak is the engine behind all of it — more sunspots, more coronal mass ejections, and more chances for the aurora to reach places it almost never goes.
- NOAA warns of minor radio blackouts as a side effect of the solar radiation, a quiet disruption most will never notice but a reminder that beauty and interference travel together.
- The viewing window is tight — 10 p.m. to 2 a.m. local time — and requires escaping city light; by Monday, the storm fades and the aurora retreats northward once more.
The northern lights are heading south this weekend, carried by a pair of geomagnetic storms that will push the aurora borealis well beyond its usual Arctic domain. Friday night opens the window first, with a Kp index of four expected to produce a display vivid enough that forecasters call it "quite pleasing" — visible across Washington, Idaho, Montana, the Dakotas, Minnesota, and parts of Maine, with Alaska and Canada holding the best odds. The viewing window runs from 10 p.m. to 2 a.m. local time, and darkness is essential: city glow will swallow the show.
Saturday raises the stakes. A minor geomagnetic storm is forecast to sweep through and push aurora visibility significantly farther south, the kind of event that sends the northern lights into skies that almost never hold them. Earlier this month, a severe storm carried the aurora as far as Texas — a preview of what an active sun can do when conditions align.
The force behind all of this is Solar Cycle 25, the sun's current 11-year peak. Heightened sunspot activity and coronal mass ejections — violent bursts of plasma and magnetic fields — are producing geomagnetic storms with unusual frequency and reach. This peak will persist through 2025 and into early 2026, meaning the weekend is an opportunity, not an anomaly.
For those who want to photograph the lights, the approach is simple: manual focus set to infinity, wide aperture, slow shutter, high ISO — or night mode on a smartphone. The only real requirement is open, dark sky. Drive north, find a hill, and wait. By Monday, the activity will have faded and the aurora will have pulled back toward the pole. The sun is generous this weekend, but only briefly.
The northern lights are coming to the northern tier of the United States this Friday night, and they're bringing company. A geomagnetic storm—a surge of energy and charged particles released from the sun—will push the aurora borealis farther south than usual, giving millions more people a chance to see the phenomenon that typically stays locked above the Arctic Circle.
On Friday, the forecast calls for a Kp index of four on a nine-point scale, which means the aurora will brighten noticeably and become what forecasters describe as "quite pleasing to look at" for anyone positioned to see it. The National Oceanic and Atmospheric Administration expects the northern lights to be visible across parts of Washington, Idaho, Montana, North Dakota, and Minnesota, with a lower but real chance in South Dakota, Wisconsin, northern Michigan, and northern Maine. Alaska and Canada will have the best odds. The viewing window is narrow: between 10 p.m. and 2 a.m. local time, and only if you can escape the glow of city lights and reach higher ground.
But the real show arrives Saturday. A minor geomagnetic storm is forecast to sweep across the region, pushing aurora visibility significantly farther south than Friday's display. This is the kind of event that can send the northern lights dancing across skies in places that rarely see them. The activity will begin to fade by Monday, but the weekend window represents a rare opportunity for people well outside the aurora's usual range.
What's driving all this is the sun itself. The star is currently in the peak phase of its 11-year cycle, known as Solar Cycle 25, a period of heightened activity marked by more sunspots and coronal mass ejections—violent bursts of plasma and magnetic fields hurled from the sun's surface. This peak will persist through 2025 and into early 2026, meaning more geomagnetic storms and more chances to see the aurora across a wider swath of the country. Earlier this month, a severe geomagnetic storm sent the northern lights as far south as Texas, a reminder of how far the phenomenon can reach when conditions align.
There's a practical cost to this activity: NOAA warns of possible minor radio blackouts caused by solar radiation, which could intermittently disrupt low-frequency navigation systems and radio signals. For most people, this will be invisible. For those wanting to photograph the aurora, the recipe is straightforward. A regular camera with manual focus set to infinity, a wide aperture, slow shutter speed, and high ISO will capture the lights. Smartphone users should enable night mode and reduce the shutter speed. The key is getting away from artificial light—drive north, climb a hill, find open sky, and wait.
The next few nights offer a window that won't stay open long. By Monday, the geomagnetic activity will have weakened, and the aurora will retreat northward again. For now, the sun is generous, and the sky is waiting.

La Conversación del Hearth Otra perspectiva de la historia
Why does the aurora move south during these storms? Is it just getting brighter, or is something else happening?
The geomagnetic storm doesn't move the aurora itself—it expands the zone where it becomes visible. The sun's particles interact with Earth's magnetic field, and during stronger storms, that interaction happens farther from the poles. It's like the aurora's reach extends.
So if I'm in, say, Wisconsin, what am I actually looking at if I see it?
You're seeing charged particles colliding with oxygen and nitrogen in the upper atmosphere. The colors—greens, reds, purples—come from which gas gets hit and at what altitude. On Friday, it might be faint. Saturday could be vivid.
Is this solar maximum thing unusual, or is it just the sun doing its thing?
It's the sun doing its thing, but it's a predictable thing. Every 11 years, the sun ramps up. We're in that window now, and it'll stay intense through 2026. So this isn't a one-night event—it's a season.
What about those radio blackouts? Should people be worried?
Most people won't notice. It's low-frequency systems—navigation, some radio bands. If you're flying or at sea, your crew knows about it. For someone watching the sky, it's background noise.
Why is the viewing window so short—just four hours?
That's when the aurora is typically most active and visible. You could see it outside that window, but those hours are your best bet. And you need darkness, so you're locked into night.
If I drive north Friday and don't see anything, should I try again Saturday?
Absolutely. Saturday's storm is stronger. You might drive two hours Friday and see nothing, then the same drive Saturday brings the whole sky alive. The difference between a Kp four and a minor geomagnetic storm is real.
