Live Aurora Outlook
Northern Lights in Alaska
Tonight's Live Forecast
Alaska needs a Kp index of roughly 1+ for visible aurora. Below is tonight's answer, computed from the live Kp reading — updated hourly, explained calmly.
Can you see the northern lights in Alaska tonight?
Close — a small uptick would put it in reach
The Kp index is currently 0, just below Alaska's approximate threshold of Kp 1. Geomagnetic activity moves in waves, so a substorm could briefly tip the odds — worth a look north if you are already somewhere dark.
Aurora in Alaska
What Alaska Needs for a Display
Alaska is the single best place in the United States to see the northern lights, and it is not close. Fairbanks and the interior sit directly beneath the auroral oval, which means aurora is visible on most clear, dark nights even at Kp 0–1 — no geomagnetic storm required. The practical limits in Alaska are darkness and weather, not the Kp index: from roughly late April through mid-August, the midnight sun keeps interior skies too bright to see anything.
Fairbanks sits at roughly 65° geomagnetic latitude — directly under the auroral oval. Aurora visibility depends on geomagnetic latitude — which differs from map latitude by up to 15 degrees — so these thresholds come from NOAA SWPC's storm-level view-line estimates, not simple map position. Treat them as odds, not guarantees: at the threshold Kp, expect a glow low on the northern horizon rather than overhead curtains.

Best Viewing Spots in Alaska
When to Look
10 PM – 2 AM local time, centered on midnight. September through March offers the darkest skies. Avoid full-moon nights and city light domes — even 30 minutes of driving makes a real difference.
Don't Refresh This Page All Winter —
get a Kp alert instead
Aurora visibility in Alaska is driven by the Kp index, so a Kp storm alert is effectively an aurora heads-up. The ResonanceOne app sends free push notifications when the Kp index reaches geomagnetic storm level (Kp 5+) — right at Alaska's visibility threshold.
To be clear: ResonanceOne is not a dedicated aurora app — no aurora map, no location-based visibility forecast. It tracks the underlying signals (Kp index, solar flares, Schumann Resonance) in one calm Activity Index, and alerts you when they spike.
Common Questions
Northern Lights in Alaska: FAQ
Can you see the northern lights in Alaska tonight?
It depends on the live Kp index. Alaska needs roughly Kp 1 or higher for aurora to be visible from its darkest northern areas. This page compares tonight's live Kp against that threshold and gives a real-time answer, updated hourly.
What Kp index do you need to see the aurora in Alaska?
Roughly Kp 1 for a glow low on the northern horizon from the state's best locations. Fairbanks sits at roughly 65° geomagnetic latitude — directly under the auroral oval. Southern parts of the state typically need 1–2 Kp steps more, and an overhead display needs a stronger storm than a horizon glow.
Where is the best place in Alaska to see the northern lights?
Murphy Dome and Cleary Summit outside Fairbanks; Denali National Park; Coldfoot and the Dalton Highway; Chena Hot Springs. The pattern behind all of them: dark skies, a low, unobstructed view to the north, and distance from city light domes.
What time should I look for the aurora in Alaska?
Between 10 PM and 2 AM local time, centered on local midnight — when your location rotates under the densest part of the auroral oval. September through March offers the darkest skies; check the moon phase too, since a full moon washes out faint displays.
How do I get an alert when the aurora might be visible in Alaska?
Aurora visibility is driven by the Kp index, so a Kp storm alert works as an aurora heads-up. The ResonanceOne app sends free push notifications when Kp reaches geomagnetic storm level — well below Alaska's everyday aurora conditions. ResonanceOne has no aurora map; it gives you the underlying geomagnetic signal, which you pair with this page's guidance.
