The turkey isn't the only thing glowing this November. Space weather experts are tracking a massive uptick in solar activity that suggests a rare holiday treat: the northern lights could be seen across the US on Thanksgiving. It sounds like a tall tale, honestly. Usually, you have to trek to the frozen reaches of Fairbanks or northern Norway to catch that haunting green shimmer. But 2026 is proving to be a wild year for the sun.
We are currently smack-dab in the middle of Solar Maximum. This is the peak of the sun's 11-year cycle, known as Solar Cycle 25. During this phase, the sun’s magnetic field flips, leading to a dramatic increase in sunspots and giant explosions of plasma called Coronal Mass Ejections (CMEs). When these CMEs slam into Earth's magnetic field, they trigger geomagnetic storms. These storms are the "engine" behind the aurora borealis, pushing the lights much further south than they usually go.
The Science of Why This Is Actually Happening
Basically, the sun is angry.
The National Oceanic and Atmospheric Administration (NOAA) and their Space Weather Prediction Center have been busy. They've been monitoring several active regions on the solar disk. If one of these regions lets loose a "halo" CME—one directed right at us—just a few days before the holiday, the timing would be perfect. It takes about two to three days for that solar wind to reach Earth.
When it arrives, it interacts with our magnetosphere. Think of it like a cosmic pinball machine. Electrons hit oxygen and nitrogen atoms in our atmosphere, releasing light. Oxygen gives you that classic ghostly green, while nitrogen can produce deep reds or purples. If the storm hits a G3 (Strong) or G4 (Severe) rating, people in states like Iowa, Pennsylvania, and even Oregon might just need to step out onto their back porch after dinner to see the show.

Light pollution is the enemy here. If you’re in the middle of Chicago or New York City, you’re probably out of luck unless the storm is truly historic (like the May 2024 event). You need dark skies.
For those in the northern tier of the US—think Washington, Montana, the Dakotas, Minnesota, Wisconsin, and Michigan—the odds are quite high. But the "auroral oval" can stretch. During significant geomagnetic events, the viewing line drops. Honestly, if you're north of the 40th parallel, you should be paying attention. This includes places like Boulder, Columbus, and Philadelphia.
The trick is the horizon.
Even if the lights aren't directly overhead, they often appear as a faint, glowing "dawn" on the northern horizon. That’s actually where the name aurora borealis comes from: "northern dawn."

Human eyes, especially in low light, struggle to pick up color. We see things in "scotopic vision," which mostly registers shades of gray. Digital sensors don't have that problem. If you suspect the northern lights could be seen across the US on Thanksgiving, grab your iPhone or Android. Use the "Night Mode" setting. Set it to a 3-to-10 second exposure and keep your hands steady.
Often, the screen will reveal a vibrant green or pink smear that looks like a gray cloud to the naked eye. It feels a bit like cheating, but it’s the best way to confirm you’re actually seeing space weather and not just light pollution from a nearby stadium.
Real-World Factors That Could Ruin the Party
Clouds. Always clouds.
November is notoriously "the gray month" for much of the Midwest and the Northeast. You could have the biggest solar storm of the century, but if there's a thick layer of stratus clouds over your house, you're seeing nothing but darkness.
There's also the moon to consider. A bright moon washes out the faint glow of the aurora. You’ll want to check the lunar phase; luckily, if the moon is a crescent or set early in the evening, the contrast will be much better.

Experts like Dr. Tamitha Skov, often called the "Space Weather Woman," frequently remind enthusiasts that these forecasts are fickle. Space weather is a lot like regular weather—sometimes the "big storm" misses us by a few thousand miles, and we get nothing but a quiet night.
How to Track the Storm in Real Time
Don't just stand outside in the cold for three hours. Use the data.
- The Kp-index: This is the scale used to characterize the magnitude of geomagnetic storms. It ranges from 0 to 9. You want to see a Kp-index of at least 5 for a chance in the northern US, and a 7 or higher if you're further south.
- The Bz Component: This is part of the Interplanetary Magnetic Field (IMF). For the northern lights to "break through" our atmosphere, the Bz needs to point south (negative). If it's pointing north, it basically bounces off our magnetic shield.
- NOAA 30-Minute Forecast: This is a map that shows the current extent and intensity of the auroral oval. It’s the most accurate "right now" tool we have.
Why This Matters More Than Just a Pretty Picture
There’s something deeply grounding about seeing the northern lights. It reminds us that we live on a planet with a thin atmosphere, protected by a magnetic field, orbiting a giant nuclear furnace.
In a world that feels increasingly digital and disconnected, a massive solar event is a physical reminder of our place in the solar system. Plus, it's a great excuse to get the family away from the TV and out into the fresh air after a heavy meal.
Actionable Steps for Thanksgiving Night
If you want to catch this event, don't leave it to chance. Start by downloading an aurora tracking app like "My Aurora Forecast" or "Aurora Alerts" a few days before Thanksgiving. These apps send push notifications when the Kp-index spikes in your specific location.
Next, scout a location. Use a "Light Pollution Map" website to find a spot within a 30-minute drive that has a clear, unobstructed view of the northern horizon. A lakefront or a high ridge is usually your best bet.
Finally, pack a "chase kit." This should include a tripod for your phone (essential for long exposures), a portable power bank because cold weather kills batteries, and a red-light flashlight to preserve your night vision. Keep checking the "Space Weather Prediction Center" website on Thanksgiving afternoon. If they issue a G2 or G3 watch, that’s your signal to head out about an hour or two after sunset. Look north, stay patient, and let your camera do the heavy lifting.
