NightHalo is a modern Northern Lights tracker built for people who actually want to see the aurora — not just read charts.
Using real-time space weather data from NOAA, NightHalo shows you when and where the aurora is most likely to appear, based on your location, sky conditions, and current geomagnetic activity.
What NightHalo shows you:
• Live aurora probability for your location
• KP index with a clear, visual indicator
• Best viewing direction so you know where to look
• Cloud cover & visibility to judge real-world conditions
• Best time to view based on forecast data
• Hourly outlook for tonight and tomorrow
Explore beyond your location:
• Watch the aurora sweep across the globe on the interactive aurora map
• Search and save custom locations anywhere in the world
• Compare forecasts for different regions before you travel
Smart alerts (optional):
• Get notified when aurora probability is high
• Choose device location or a custom place
• Control alert timing and quiet hours
NightHalo is designed to be calm, accurate, and easy to understand — whether you’re chasing your first aurora or planning serious night photography.
No accounts. No clutter. Just clear aurora forecasting.
