Northern Lights in Wyoming
Tonight's Live Forecast
Wyoming needs a Kp index of roughly 6+ for visible aurora. Below is tonight's answer, computed from the live Kp reading — updated hourly, explained calmly.

Unlikely in Wyoming tonight
The Kp index is currently 3, below the roughly Kp 6 that Wyoming needs for visible aurora. Watch for geomagnetic storm alerts — when Kp reaches 6+, tonight's answer changes.

What Wyoming Needs for a Display
Wyoming trades latitude for altitude and darkness. A moderate-to-strong storm (Kp 6–7) can produce a northern-horizon display from the Bighorns and the Yellowstone country, and because so much of the state has essentially zero light pollution, marginal events are visible here that city dwellers further north would miss entirely.
Northern Wyoming responds at Kp 6–7; the state's altitude and darkness lower the practical bar. 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.

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.

Aurora visibility in Wyoming 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 6+ to match Wyoming'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.
