Get away from the city, face north, and wait.
Tonight, the sun's restless energy reaches down into the upper atmosphere of the northern United States, setting the sky alight with the ancient fire of the aurora borealis. A mild but meaningful geomagnetic storm — rated G1, with a Kp index of 5 — will carry the northern lights across more than a dozen states, from the Pacific Northwest to the coast of New England, between 10 p.m. and 2 a.m. Eastern time. It is a reminder that we live not in isolation beneath a fixed and silent sky, but inside a dynamic solar system that occasionally makes its presence luminously known. For those willing to seek darkness and surrender to patience, the reward is one of nature's oldest and most humbling spectacles.
- A surge of charged solar particles is racing toward Earth's magnetic field tonight, strong enough to push the northern lights far below their usual Arctic domain.
- More than twelve northern states — from Washington to Maine — fall within the aurora's visibility band, raising the rare possibility of a sky show for millions of Americans.
- Light pollution is the enemy: urban residents in the forecast zone will see nothing, and the only path to the lights runs through dark rural fields and unobstructed northern horizons.
- The naked eye may catch only a ghostly gray shimmer, but a smartphone camera on long exposure will unlock the full palette of greens, pinks, and purples the aurora is famous for.
- With the sun approaching its 11-year solar maximum through 2025, tonight is not a singular event but the opening of a season — more storms, more light, more chances to look up.
Tonight, across the northern tier of the United States, the sky may do something extraordinary. A G1 geomagnetic storm — the mildest on the scale, but potent enough to matter — is pushing the aurora borealis well south of its usual Arctic territory. NOAA's Space Weather Prediction Center has issued a forecast covering more than a dozen states, from Washington and Montana in the west to Vermont and Maine in the east, with the best viewing window running from 10 p.m. to 2 a.m. Eastern time.
The science behind the spectacle is elegant: solar activity has flung charged particles toward Earth, and as they collide with gases high in the atmosphere, they release light — the greens, pinks, and purples that have transfixed humanity for millennia. Tonight's storm carries a Kp index of 5 out of 9, enough to extend the aurora's reach across a broad continental band.
But geography alone won't do it. Darkness is the essential ingredient. Anyone hoping to see the lights must leave the city behind entirely — a state park, a rural field, an unobstructed northern horizon. From a backyard in any lit suburb, the show simply won't exist. And even in true darkness, the aurora can surprise first-timers: to the naked eye it often appears as a faint, ghostly haze. A smartphone camera on long exposure, however, will reveal what the eye misses — the full, vivid spectrum that makes the aurora legendary.
For those who miss tonight's window, the consolation is genuine. The sun is climbing toward solar maximum in 2025, the peak of its 11-year activity cycle. Geomagnetic storms will grow more frequent and more powerful in the months ahead, and the northern lights will keep returning — pushing farther south each time. The season of aurora, for much of the northern United States, has only just begun.
Tonight, if you're willing to drive north and stay up past midnight, you might see something most Americans never do: the sky dancing in green and purple light. The aurora borealis is coming to the northern United States, and it's arriving farther south than usual. The National Oceanic and Atmospheric Administration's Space Weather Prediction Center has issued a forecast for a G1 geomagnetic storm—the mildest category on the scale, but potent enough to push the northern lights well beyond their typical Arctic home.
The mechanism is straightforward. A surge in solar activity has sent charged particles hurtling toward Earth's magnetic field and upper atmosphere. When those particles collide with gases in the thin air above us, they emit light—the ethereal greens, pinks, and purples that have captivated humans for millennia. Tonight's storm carries a Kp index rating of 5 out of 9, which means the aurora's visibility line extends across a broad band of the continent. If you live in Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New York, Vermont, New Hampshire, or Maine, you're in the zone. Even the northernmost corners of Iowa might catch a glimpse.
But seeing the lights requires more than geography. It requires darkness. The single most important factor in a successful viewing experience is escaping light pollution entirely. This means leaving town. Head to a state park, a remote campsite, or a rural field where the northern horizon is unobstructed and the sky is genuinely dark. Urban dwellers in the forecast zone will see nothing from their backyards. The rule is simple: get away from the city, face north, and wait.
Timing matters too. The lights are expected to be most active between 10 p.m. and 2 a.m. Eastern time, with the most vivid displays typically peaking around midnight. But aurora displays are unpredictable. They can vanish in minutes or persist for hours. Patience is not optional. There's also a perceptual trick worth knowing: to the naked eye, the aurora often appears as a grayish or whitish cloud, almost ghostly and underwhelming. But a smartphone camera set to a long exposure will reveal what your eyes cannot—the full spectrum of color that makes the aurora famous. Many people who see the lights in person for the first time are surprised by how faint they appear until they look at their phone's screen.
If you miss tonight's show, the consolation is real. The sun is currently in the ascending phase of its 11-year activity cycle, and 2025 marks the approach of solar maximum—the peak of solar intensity. This means geomagnetic storms will become more frequent and potentially more powerful in the months ahead. The northern lights will return, and they'll keep returning, pushing farther south each time the sun throws a tantrum. For stargazers in the northern half of the country, the season of aurora has only just begun.

Why is this storm only a G1 if it's pushing the lights so far south?
The scale is relative. A G1 is minor by the standards of what the sun can do—we go up to G5. But even a minor storm has enough energy to disrupt the magnetosphere enough that the aurora becomes visible hundreds of miles farther south than normal. It's like the difference between a light breeze and a strong wind; both move air, but the scale tells you how much.
So if someone in Iowa actually sees it, what would they be looking at?
Probably a faint glow on the northern horizon, maybe some color if they're lucky and the display is strong. It won't be the curtains of light you see in Alaska. But it's still the same phenomenon—it's still the sun's energy hitting Earth's atmosphere. That's the remarkable part.
Why does a camera see colors the eye doesn't?
The human eye is terrible in low light. Our color vision shuts down almost entirely in darkness. A camera sensor can gather light over several seconds and build up an image our eyes never see in real time. You're not missing the colors—they're genuinely there. Your eye just can't perceive them.
Is this a sign the sun is becoming dangerous?
Not dangerous in the way you might think. A G1 storm is routine. What's notable is that we're climbing toward solar maximum, so we'll see more of these. But Earth's magnetosphere is designed to handle this. The real effect is on satellites and power grids—not on people standing in a field watching the sky.
How long does someone need to stay out there to see it?
That's the gamble. Could be fifteen minutes. Could be three hours. The aurora is intermittent. You show up, you find your dark spot, and you wait. Some people see nothing. Others see the whole sky light up. There's no guarantee.
