About AuroraWatch: Aurora Alerts

AuroraWatch: Aurora Alerts is a free, ad-free iPhone and Apple Watch app that forecasts the Aurora Borealis and Aurora Australis using NOAA’s OVATION aurora model, the live Kp index, NOAA SWPC solar wind data, USGS magnetometers and local cloud cover and moon illumination, with optional Pro features including private on-device AI summaries, widgets, Live Activity and an Apple Watch dashboard.

AuroraWatch: Aurora Alerts is built for aurora chasers, photographers, and curious sky watchers in both hemispheres. Whether you are checking whether the Aurora Australis might appear over Tasmania, or whether a geomagnetic storm could push the Northern Lights over Iceland, the app combines global space-weather inputs with your local weather so you can decide when it is worth heading outside.

The app launched on iOS and is developed independently. Core forecasts, maps, KP index, solar wind charts, and NOAA solar imagery are free. Optional AuroraWatch Pro adds Home Screen widgets, Live Activity, Aurora Now alerts, deeper NOAA history charts, and premium themes.

What data powers the app?

Aurora forecasts use NOAA Space Weather Prediction Center (SWPC) products, including the OVATION aurora model and near-real-time solar wind measurements from spacecraft at the L1 point (such as DSCOVR). Local cloud cover and conditions use Apple WeatherKit where available. NASA Solar Dynamics Observatory (SDO) imagery powers the Solar tab. See our data sources page for full attribution and links.

Platforms

AuroraWatch: Aurora Alerts is available on iPhone and iPad through the App Store. An Apple Watch companion is planned.
