Can you see the northern lights in Minnesota tonight?
Unlikely: Kp 0.00 at 4:09 AM CDT falls short of the Kp 2 or so that Minnesota's northern horizon requires.

Kp from NOAA SWPC estimated planetary K index. The NWS DLH gridded forecast provides cloud cover for Voyageurs National Park.
At Voyageurs National Park, nautical darkness begins at 7:34 PM and holds until 6:22 AM CDT. Tonight's moon, in its waxing crescent phase, shows 4 percent lit. The sun and moon positions, computed for the date and the viewing spot, supply both numbers, and no forecast plays a part.
What is Kp?
A 0-9 scale called Kp rates the current disturbance of Earth's magnetic field. Its name comes from planetarische Kennziffer, German for planetary index. Thirteen observatories worldwide take the measurements. Higher values mean the aurora reaches further south. Most of the northern US needs a Kp of 5 or higher, while northern Alaska sees it at Kp 0. Full Kp guide.
Why Minnesota needs Kp 2
Because the aurora follows the magnetic field rather than the equator, geomagnetic latitude matters more than map latitude. At Minnesota's northern edge, the reading is 57.9° geomagnetic; the oval only draws level with that latitude at about Kp 2, and the Kp number already includes roughly 5 degrees of cushion, because the high-altitude aurora hangs low on the horizon.
Where to watch from in Minnesota
All three spots in Minnesota can differ in cloud cover, so all three are worth a look. Cook County, Grand Marais looks clearest tonight, at 58% cover.
| Spot | Cloud tonight | Clearest hour | Nearest town |
|---|---|---|---|
| Voyageurs National Park | 82% Mostly cloudy | 1:00 AM CDT | Ranier |
| Cook County, Grand Marais | 58% Partly cloudy | 3:00 AM CDT | Grand Marais |
| Lake Bemidji State Park | 83% Mostly cloudy | 11:00 PM CDT | Bemidji |
Voyageurs National Park near Ranier is a Minnesota aurora staple under Kp 2 activity, which occurs on many nights a year. Cook County near Grand Marais offers a dramatic north shore, and Lake Bemidji State Park near Bemidji is a solid inland choice. Equinoxes are the most active. Dark nights run October through March.
Can the northern lights reach Duluth and Minneapolis tonight?
| City | Kp needed | Right now |
|---|---|---|
| Duluth | Kp 3 | No chance |
| Minneapolis | Kp 4 | No chance |
Each city's Kp value comes from its own coordinates and geomagnetic latitude, so the further south a city is in the state, the higher the Kp it needs.
Cloud cover, averaged over tonight's viewing window for each location, comes from NWS gridded forecasts.
Was there aurora last night in Minnesota?
The night of October 12 reached Kp 3.33, at or above the 2 that Minnesota needs, so the aurora was in range.
The most recent night in range was October 12, 2026, when the night's highest Kp reached 3.33.
193 nights so far in 2026 have been in range for Minnesota, against a yearly average of 268.3 across the complete years since 1994. The year's highest night Kp so far is 8.67, set on January 19, 2026.

Local time 9 pm to 3 am is the span of a night. The night's Kp is the highest among the three hour windows overlapping those hours. A night is in range when that Kp reached the threshold the state needs, which comes from where the northern edge of the state sits in geomagnetic latitude. Cloud is not in the record, so in range means the aurora was in range, not that anyone saw it. Figures are NOAA Space Weather Prediction Center daily geomagnetic data from 1994 on.
The next three days

Watching from Minnesota
- The aurora seldom appears overhead in Minnesota; look at the northern horizon instead.
- Away from town lights, allow 20 minutes for your eyes to adjust.
- The aurora is most active from 10pm to 2am local, near magnetic midnight.
- A phone exposure of 3-5 seconds picks up color the eye cannot; a grey glow can photograph green.
