How we forecast

We combine three inputs to produce a single cloud-adjusted visibility probability:

Kp index
NOAA SWPC's 3-hour geomagnetic activity forecast — how strong the aurora-driving storms are.
Auroral oval
The boundary 66.5° − 2.5 · Kp — the lowest latitude where aurora is normally visible.
Local clouds
Open-Meteo's hourly cloud cover for your location. Heavy clouds reduce visibility proportionally.
