Northern Lights in Trondheim
Trondheim is situated in Norway. While not directly under the standard auroral oval, its northern location at 63.4° makes it a very reliable viewing spot. Monitor local weather carefully, as clear skies are your biggest hurdle in this prime location.

FAQ
What Kp index do I need to see the northern lights in Trondheim?
In Trondheim, you usually need at least Kp 2 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 3.7 to 5.7. You should have a good chance of seeing the aurora if the sky is clear.
