Aurora Borealis in Duluth, United States
Duluth is situated in United States's Minnesota area. At a latitude of 46.8°, you will need a historically massive solar event to push the lights this far south. While it takes patience and luck, catching a display from here is an unforgettable experience.
FAQ
What Kp index do I need to see the northern lights in Duluth?
In Duluth, you usually need at least Kp 6 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 1.3 to 2.7. That is below the usual Kp index threshold for Duluth, so seeing the aurora is unlikely.
