Northcall
Know when the northern lights are actually worth going out for.
Northcall emails you when NOAA's live space-weather data says the aurora is likely visible in your region, so you can stop refreshing forecast apps and stop missing the good nights.

What you get
- Email alerts for your region: you pick it at checkout (Alaska, the northern tier states, the Great Lakes, New England and more).
- More than the Kp number. Alerts weigh the solar-wind feed (magnetic field direction and speed) along with Kp, because that's what decides whether a storm turns into visible aurora.
- Few, meaningful emails. We'd rather send three good alerts than thirty maybes.
Founding pass: please read
- Northcall is new. Alerts start by 2026-12-15. If they don't, you're refunded in full, automatically. You don't need to ask.
- Your 12 months start the day alerts start, not the day you pay.
- Aurora forecasting is uncertain. An alert is an estimate from public data, not a guarantee, and clouds and city light still matter.
- Changed your mind? Email us within 14 days for a full refund, no questions asked.
