Live Aurora Outlook
Northern Lights in Oregon
Tonight's Live Forecast
Oregon needs a Kp index of roughly 7+ 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 Oregon tonight?
Unlikely in Oregon tonight
The Kp index is currently 0, below the roughly Kp 7 that Oregon needs for visible aurora. Watch for geomagnetic storm alerts — when Kp reaches 7+, tonight's answer changes.
Aurora in Oregon
What Oregon Needs for a Display
Oregon is on NOAA's Kp 7 view line, so aurora here means a strong G3 storm — a handful of chances per year near solar maximum. The state compensates with world-class darkness: the Oregon Outback in the southeast is a certified Dark Sky Sanctuary, and the high desert east of the Cascades has clean, dry northern horizons that make the most of every event.
NOAA's Kp 7 (G3 storm) view line reaches Oregon. 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 Oregon
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.

get a Kp alert instead
Aurora visibility in Oregon 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+) — watch for readings of 7+ to match Oregon's 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 Oregon: FAQ
Can you see the northern lights in Oregon tonight?
It depends on the live Kp index. Oregon needs roughly Kp 7 or higher for aurora to be visible from its darkest northern areas — a strong geomagnetic storm. 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 Oregon?
Roughly Kp 7 for a glow low on the northern horizon from the state's best locations. NOAA's Kp 7 (G3 storm) view line reaches Oregon. 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 Oregon to see the northern lights?
Columbia River Gorge east of Portland (Rowena Crest); Central Oregon high desert near Prineville; Oregon Outback (Lake County). 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 Oregon?
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 Oregon?
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 — and Oregon's threshold of roughly Kp 7 is exactly that storm territory. ResonanceOne has no aurora map; it gives you the underlying geomagnetic signal, which you pair with this page's guidance.
