Aurora is visible from Minnesota several times a year. In central Minnesota the geomagnetic latitude is about 55°, so the northern lights usually need a Kp index of about 3.5 or higher to appear low on the northern horizon; the north of the state (around Northwest Angle State Forest) needs about Kp 2.5.

Approximate Kp for aurora low on the northern horizon (camera-visible). Higher Kp lets it climb higher and show color to the eye.

How to photograph the northern lights
- Watch the live Kp forecast above and NOAA's 30-minute aurora forecast; storms often peak between 10 p.m. and 2 a.m.
- Find an unobstructed view to the north — a lake, open field or ridge — away from town lights.
- Start at ISO 1600–3200, f/2.8 or faster, 5–15 seconds; shorter exposures keep fast-moving curtains sharp.
- Your camera sees aurora as green or red long before your eyes do — take test shots whenever Kp is near the threshold.
- Moonlight lights the foreground but washes out faint aurora; strong storms are still worth shooting under a bright moon.
FAQ
Can you see the northern lights in Minnesota?
Yes, several times a year. Central Minnesota usually needs about Kp 3.5; the north about Kp 2.5.
What Kp index do I need?
Roughly Kp 3.5+ for central Minnesota. Kp is a 0–9 scale of geomagnetic activity; each step moves the aurora's southern edge a few degrees of latitude.
Where is the best place to see the aurora in Minnesota?
Dark sites with a clear northern view, such as Voyageurs National Park, Itasca State Park, Judge C. R. Magney State Park.
