Stop refreshing.
Let the sky tell you.
Free tells you tonight looks good. Pro watches the live data all night and taps you on the shoulder the moment it's actually worth stepping outside, so you catch the display instead of sleeping through it.
Three ways to get Pro. Only one of them renews.
A week for one trip, a year for a season, or once for good. The season is short, August to April at most locations, and the free forecast stays free whatever you choose.
- Live Kp, Bz & cloud cover for 20 locations
- Tonight's probability, checked against field reports
- Five-night outlook: darkness, moon and Kp
- Live aurora map, any point on Earth
- Your own saved spot
- All location guides & Kp scale reference
- Push alert at your own Kp threshold (1 location, anywhere on Earth)
Everything in Free, plus the hour-by-hour timing and the alerts that watch the sky for you. The only question is how long.
For people who chase the sky all season.

A good forecast still isn't a good alarm clock
You're asleep when it happens
The best displays often peak between midnight and 3am. Checking an app before bed tells you nothing about 2am.
Kp alone doesn't tell you when
A "good night" forecast can mean a 20-minute window at 11pm or a slow build at 3am. Free gives you tonight's odds, not the moment.
Clouds and moonlight matter
A Kp 6 storm behind cloud is invisible. A bright gibbous moon washes out a faint Kp 3 display. Both change hour to hour.
Real-time data, working for you all night
Hour-by-hour timing
See exactly which hours tonight are worth being outside for, not just a single tonight-average number.
Moon-aware alerts
We factor in moon phase and wash-out so you're not standing outside for a display the moonlight will erase.
The earliest possible warning
An evening heads-up tells you tonight's peak hours before it gets dark. Then SOLAR-1 gives 15 to 60 minutes of live lead time: Pro pushes calibrated probability and Bz-flip alerts the moment they happen, tuned to your exact location, not a flat Kp number.

No ads. No selling your data. No VC growth targets.
Live NOAA and SOLAR-1 feeds, hourly cloud data for 20 locations, and push infrastructure that watches the sky all night, none of that is free to run, every night, all season. Pro funds the data pipeline directly instead of funding an ad network or a data broker. That's also why it's a yearly plan, a one-time payment, or a week for one trip, not a subscription designed to be forgotten.
Built by Aurora operators, not aggregators
This forecast is run by the team behind Northern Lights Resort & Spa, a TripAdvisor Best-of-the-Best property near Whitehorse, Yukon. We use SOLAR-1 (not the retired DSCOVR) and magnetic latitude (not a map) because that's what actually predicts what appears overhead, the same calibration Pro's alerts are built on.
Before you decide
No. $19.99/year with nothing hidden, or pay $34.99 once and never see a charge again. No weekly billing, no auto-upgrade tricks.
It is, and stays that way, all 20 locations, tonight's probability, the five-night outlook, the map and every guide are free forever. Pro is the extra layer on top: hourly timing, moon and flare data, and alerts that watch the sky while you sleep.
Yes. Annual and Lifetime work on up to 3 devices, the Week Pass on 2. After you buy, Settings shows a restore code; enter it on the other device and Pro moves across. On iPhone the installed app and Safari count as separate devices, so install the app first, then buy or restore inside it.
Yes, from the installed app. Open the site in Safari, tap Share, then Add to Home Screen, and turn alerts on inside that app. iPhone does not deliver web push to a normal browser tab, which is Apple's rule, not ours.
Settings. Under the plan badge there is a box for restore and access codes. Install the app first if you are on iPhone, then enter the code inside it, so Pro lands on the copy you will actually use.
You can: SWPC and SOLAR-1 are public data. But raw Kp doesn't tell you Whitehorse needs less of it than Tromsø at 63° vs 67° magnetic, doesn't fold in your local cloud cover, and won't wake you when Bz turns south at 2am. That correlation and alerting is what Pro pays for.
It's the team behind Northern Lights Resort & Spa near Whitehorse, Yukon, a TripAdvisor Best-of-the-Best property with 1,100+ reviews, watching this sky professionally every season.
