You’re standing in a frozen field in Iceland or maybe a dark driveway in Fairbanks, staring at a smudge in the sky. It looks like a faint, greyish cloud. Maybe it’s a bit milky. You’re cold, your toes are numb, and you’re starting to think the "aurora borealis" is a giant marketing scam.
Then you hold up your iPhone or Pixel.
The screen explodes with neon green.
It’s a bizarre, almost spiritual moment when you realize your phone is seeing a reality that your biology is literally incapable of processing. Most people think they need a $3,000 DSLR and a tripod the size of a small tree to capture this. They don't. Honestly, modern sensor technology has reached a point where your pocket slab is often better at "seeing" the lights than your own retinas.
If you want to know how to see the northern lights with your phone, you first have to understand why your eyes are failing you. Human night vision relies on rod cells. Rods are great for movement, but they’re colorblind. The aurora has to be incredibly intense before our brains register the greens and purples. Digital sensors don't have that biological limitation. They just soak up photons until the colors bleed through.
The gear you actually need (and the stuff you don't)
Don't buy a lens kit for your phone. Just don't. Those clip-on wide-angle lenses usually add blur and chromatic aberration that ruins the crispness of the stars. What you actually need is stability.
Gravity is your enemy here.
Even if you think you have steady hands, you don't. Not for a three-second exposure. If you’re serious about how to see the northern lights with your phone, grab a cheap GorillaPod or even just lean your phone against a rock. If you’re desperate, I’ve seen people shove their phone into a boot on the ground to keep it upright. It works.
Another thing: glass. If you're shooting through a window—maybe you’re on one of those specialized "aurora flights" or staying in a glass igloo—you have to get the lens flush against the pane. Any gap will catch the reflection of the interior lights, and your photo will look like a blurry mess of hotel room lamps instead of the cosmos.

Why Night Mode is your best friend
Most modern flagships—think iPhone 12 and up, or the Samsung S21 series onwards—have an automated "Night Mode." This isn't just one photo. It’s a stack. The phone takes a dozen shots at different exposures and stitches them together using computational photography.
On an iPhone, when it detects darkness, that little yellow moon icon appears. Don't just let it do its thing at "Auto." Tap it and slide the timer to the maximum, usually 10 or 30 seconds.
Wait.
The 30-second option only appears if the phone is perfectly still, usually on a tripod. If you're holding it, the software caps you at 10 seconds because it knows you're a shaky human. This is why the tripod is the single most important "hack" for the northern lights.
The manual settings that change everything
Sometimes the "smart" AI in your phone tries to be too clever. It might try to brighten the sky so much that the black night turns into a grainy, muddy grey. That's when you go manual.
If you're on Android, look for "Pro Mode." On iPhone, you might need a third-party app like Halide or NightCap, though the native camera is getting scarily good.
ISO is the big one. Think of ISO as your camera’s sensitivity to light. You want it high enough to see the aurora, but low enough to avoid "noise" (that grainy static). For a bright aurora, 800 to 1600 is the sweet spot. If it's a faint "sub-visual" aurora, you might push to 3200, but expect some grain.
Shutter speed matters next. If the lights are dancing fast—rippling like curtains in a breeze—you want a shorter shutter speed, maybe 2 to 5 seconds. If you leave it open for 20 seconds, the movement blurs together, and you just get a green blob instead of distinct pillars.

Focus is the silent killer. Your phone will try to autofocus on the darkness and fail. It’ll hunt back and forth, and your stars will look like fuzzy marshmallows. Set your focus to "Infinity." In many apps, this is represented by a mountain icon. Once you lock that, don't touch it.
Where to actually point the thing
It sounds stupid, but look North.
I’ve seen tourists in Iceland pointing their phones South toward the lights of Reykjavik because they saw a glow. That’s light pollution, folks. Unless there is a massive geomagnetic storm (like the G4 or G5 storms we saw in May 2024), the action is going to be on the northern horizon.
Use an app. "My Aurora Forecast" is a standard, but "Space Weather Live" is what the nerds use. Look at the Kp-index. A Kp-0 or Kp-1 means stay in bed. Kp-4 means get your boots on. Kp-7 means the sky is falling (in a good way).
But don't obsess over the numbers. The Kp-index is an average. You can have a "substorm" occur during a Kp-2 night that produces a 15-minute burst of incredible activity.
The cold is trying to kill your battery
Lithium-ion batteries hate the Arctic. Your phone will go from 80% to "Dead" in six minutes if it's -20°C.
Keep your phone in an internal pocket, close to your body heat, until the moment you're ready to shoot. Carry a power bank. Even better, tape a hand warmer to the back of your phone. It looks ridiculous, but it keeps the battery chemistry moving.
Editing without ruining the vibe
The photo you take will probably look a bit flat. That’s okay. When you start editing, be careful with the "Saturation" slider.

Amateurs crank saturation to 100% until the green looks like radioactive waste. It looks fake because it is. Instead, play with "Vibrance." It’s a smarter tool that boosts the less-saturated colors without blowing out the ones that are already bright.
Bring the "Black Point" up. This makes the sky look truly black rather than a dark navy blue. It creates contrast, making the aurora "pop" off the screen.
Beyond the Green: Hunting for the "Steve" and the Pinks
Sometimes you’ll see a purple or pink fringe on the bottom of the green curtains. This is rare. It happens when solar particles penetrate deeper into the atmosphere and hit nitrogen instead of oxygen.
If you see this, shorten your shutter speed immediately. Pinks move fast.
Then there’s "STEVE" (Strong Thermal Emission Velocity Enhancement). It looks like a skinny mauve or purple ribbon stretching across the sky from East to West. It isn't actually an aurora; it’s a stream of hot gas. If you see STEVE, point your phone and pray, because it usually doesn't last long, and the photos are breathtaking.
Common mistakes to avoid
- Flash: Turn it off. Seriously. You aren't going to light up a solar wind 100 kilometers away with a tiny LED. You’ll just blind everyone else standing in the field and earn yourself some very angry glares.
- Screen Brightness: Turn it all the way down. Your eyes need about 20 minutes to adjust to the dark. If you keep staring at a bright screen, you’ll never see the faint movement of the lights with your naked eye.
- Dirty Lenses: Fingerprint oil smudges the light. Wipe your lens with a microfiber cloth before you start. That "glow" around the stars in your photos? That's usually just pizza grease from your lunch.
Actionable steps for your next hunt
If you are heading out tonight or planning a trip to the auroral oval, do these three things right now:
- Download a long-exposure app if your native camera doesn't allow manual control over shutter speed.
- Test your "Infinity Focus" during the day. Point your phone at a very distant mountain or building, lock the focus, and see where that slider sits.
- Buy a tripod mount. You don't need a full tripod if you don't want to carry one; a simple plastic clamp that screws onto a standard mount is enough to let you steady the phone against a fence or car roof.
- Check the moon phase. A full moon is a giant natural lightbulb. It’ll wash out the faint lights, but it can actually make for better photos by illuminating the landscape (mountains, trees) in the foreground. If you want the absolute darkest skies for the "faint" stuff, aim for a New Moon.
Capturing the northern lights isn't about having the best gear anymore. It's about understanding how to trick your phone's sensor into staying open long enough to see what your eyes can't. Be patient. It’s a waiting game. The sun has been incredibly active lately as we head toward the solar maximum, so there has never been a better time to try this.
Stay warm, keep your phone inside your jacket, and remember to actually look up with your own eyes once in a while, even if all you see is a greyish cloud. Now you know the truth: the color is there, whether you can see it or not.
