We see the aurora coming before it arrives
Is tonight worth going outside?
Aurora, meteor showers, and stargazing forecasts for your exact location, driven by real-time solar wind physics, your cloud forecast, and the moon. One verdict for your eyes, one for your camera.
The solar wind reaching Earth in ~45 minutes is carrying real aurora energy, so activity should climb within the hour. Check your city below.

Where aurora is most likely in the US tonight
Kp running at 3.8 · updated 5:38 PMRanked live from the incoming solar wind, each city's own Kp threshold, tonight's clouds, and darkness.
Nowcast, not Kp guesswork
NOAA satellites measure the solar wind 930,000 miles before it reaches Earth. We read it and start the clock, so you get "go outside 10:40–11:20 PM" instead of a number to decode.
Eye verdict + camera verdict
Aurora is photographable from mid-latitudes far more often than it's visible. We're the only forecast that models both thresholds, with camera settings for tonight's conditions.
Confirmed by real observers
One-tap sighting reports from people near you add live ground truth on top of the forecast, so you get the model's answer and what the sky is actually doing.
