What it takes to see the aurora borealis (northern lights) from Willow
Aurora visibility is set by your geomagnetic latitude — your position relative to Earth's magnetic pole, not the geographic one. Willow sits at 61.4° geomagnetic. The auroral oval hovers near 66° in quiet conditions and expands toward the equator as geomagnetic storms strengthen: roughly 2° per step of the Kp index. That puts Willow in or near the auroral zone — displays are possible on many active nights, not just during big storms.
How to actually catch it
- Get away from city lights with a clear view of the northern horizon — light pollution is the #1 killer of borderline displays.
- Best window: 22:00–02:00 local time; best seasons: around the equinoxes, and dark winter months at high latitudes.
- Your camera sees more than your eyes: a 5-10s phone night-mode exposure reveals green/red glow invisible to the naked eye.

FAQ
Can I see the northern lights tonight in Willow?
Good odds: tonight's Kp is 7, above the Kp 2.3 Willow needs. Get away from city lights and watch the northern horizon between about 22:00 and 02:00. Updated every 30 minutes from NOAA SWPC data.
Can you see the aurora from Willow?
Yes, when geomagnetic activity is strong enough. Willow sits at geomagnetic latitude 61.4°, which means the aurora becomes visible on the northern horizon at roughly Kp 2.3 — on many active nights.
What Kp index does Willow need for aurora?
About Kp 2.3. The auroral oval sits near 66° geomagnetic latitude in quiet conditions and pushes roughly 2° toward the equator with each Kp step; Willow's geomagnetic latitude is 61.4°. You don't need the oval directly overhead — NOAA notes the aurora can be seen on the horizon from up to 1000 km away, but that reach grows with the storm: this figure credits none of it near the oval, where low-Kp aurora is faint and low, and up to 2.5 Kp at mid-latitudes, where storm aurora is tall and bright.
Which direction should I look for the aurora in Willow?
North. From Willow the auroral oval lies toward the north magnetic pole, so the aurora appears low on the northern horizon first. Pick a spot with an open northward view, away from city lights — your phone's night mode picks up glow your eyes miss.
When is the best time to see the aurora?
Around local midnight (22:00–02:00), on dark clear nights away from city lights, and statistically around the equinoxes (March/April and September/October). Solar maximum — happening now — delivers the most storms.
