Northern Lights in Ketchikan Tonight
Live forecast for Ketchikan, Alaska: real-time solar wind measured 930,000 miles upstream, NOAA's OVATION model, your cloud forecast, and tonight's darkness, with one verdict for your eyes and one for your phone camera.
Good odds for the naked eye tonight (72%), and a phone camera is even more likely to catch it (84%). Kp is 1.3 right now, and Ketchikan needs Kp 2.5+ for eyes and Kp 1+ for a phone camera. The best window is 11 PM–1 AM with 1% clouds and a forecast Kp up to 4.3.
Tonight's aurora odds
Your chance of catching aurora at any point tonight, combining the Kp forecast for tonight's dark hours, the cloud forecast, and the moon.
How we get this: forecast Kp peaks at 4.7 tonight, a 96% chance of reaching your eye threshold (Kp 2.5+) and 98% for camera (Kp 1+), times a 86% chance of usable sky in your clearest dark hours, minus a moonlight penalty (68% illuminated).

Kp 1.3 is well below the Kp 2.5 this location needs. No amount of dark sky changes the physics tonight.
Kp 1.3 clears your camera threshold (Kp 1) but not your eye threshold (Kp 2.5). Your eyes may see nothing while a 3-second exposure shows green. That is the most common way mid-latitude aurora gets "seen."
📸 Point north. Night mode / 3s exposure, ISO 1600-3200, focus to infinity, brace the phone or use a tripod. Frame away from the moon.

Aurora viewing in Ketchikan: what it takes
Ketchikan sits at magnetic latitude 59.2°, the number that actually decides your aurora odds (it differs from geographic latitude because Earth's magnetic pole sits over the Canadian Arctic, which is why the Midwest outperforms Europe at the same map latitude). From here, aurora appears low on the northern horizon at roughly Kp 2.5, fills the northern sky around Kp 3.5, and can pass overhead at Kp 4+. Eye-visible displays happen dozens of nights per year.
The threshold most sites won't tell you: your phone camera only needs about Kp 1. A 3-second night-mode exposure collects light your dark-adapted eyes cannot, so on many nights the honest answer is "no to your eyes, yes to your camera." That's why this page gives two verdicts.
Where to watch near Ketchikan
- Chena Lakes Recreation Area ↗ (841 mi), Bortle 2. The classic Fairbanks-area aurora spot, 30 minutes from town.
- Denali National Park ↗ (858 mi), Bortle 1. Six million acres of wilderness under the auroral oval: aurora on most clear winter nights.
- Cleary Summit ↗ (858 mi), Bortle 2. Ridge-top pullouts north of Fairbanks with 360° horizons, a world-famous aurora overlook.
- No time for a drive? Any spot with a dark, unobstructed northern horizon (a lakeshore, a ridge, farmland north of the city) beats a bright parking lot by a full activity level.
Northern lights in Ketchikan: FAQ
›Can you see the northern lights in Ketchikan tonight?
It depends on tonight's geomagnetic activity: Ketchikan sits at magnetic latitude 59.2°, so aurora becomes visible on the northern horizon at roughly Kp 2.5+ and can appear overhead at Kp 4+. The live forecast at the top of this page combines the real-time solar wind, NOAA's OVATION model, tonight's cloud cover, and darkness to give you a straight yes/no answer, updated every couple of minutes.
›What Kp index does Ketchikan need for aurora?
About Kp 2.5 for a visible glow on the northern horizon, Kp 4+ for overhead displays, and only about Kp 1 for a phone camera on night mode to capture it. Camera thresholds are lower because long exposures pick up sub-visual light your eyes can't.
›How often can you see the northern lights in Ketchikan?
At magnetic latitude 59.2°, Ketchikan sees eye-visible aurora dozens of nights per year. We're near solar maximum of Solar Cycle 25, so activity through 2026–2027 runs well above average.
›Where should I go to watch aurora near Ketchikan?
Get away from city light and find an unobstructed view to the north. The best nearby dark-sky options are Chena Lakes Recreation Area (841 mi), Denali National Park (858 mi), Cleary Summit (858 mi). Even a rural road 20–30 minutes north of town dramatically improves what you'll see.
›What's the best time of night to see aurora in Ketchikan?
Statistically 10 PM to 2 AM local time, when your location rotates under the strongest part of the auroral oval, though substorms can fire at any dark hour. Our best-window forecast above combines darkness, clouds, and predicted Kp for tonight specifically.
