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.
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 flat yearly or one-time fee, 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.
One plan. No weekly subscription, ever.
The season is short: Aug to April at most locations. Pick the plan and stop missing nights.

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, 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.
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.
