FAQ
What Kp index do I need to see the northern lights in Ylläs?
In Ylläs, you usually need at least Kp 1 to have a reasonable chance of seeing the northern lights. Lower Kp can still bring a faint aurora display low on the northern horizon, but it is less common.
This is based on magnetic latitude, and Kp index is a global geomagnetic index, so treat it as a rule of thumb, not a location-specific guarantee.
Tonight, the NOAA Kp index forecast is 3.0 to 3.8. You should have a good chance of seeing the aurora if the sky is clear.
