AuroraWatch UK is a geomagnetic activity and weather alert service, which allows you to monitor the UK’s geomagnetic activity in real time and receive push notifications when an aurora may be visible from the UK.

The app allows you to view the most up-to-date data and historical trends to help you understand the geomagnetic activity in the UK and make predictions about when and where the aurora may be seen.

It will also alert you to any geomagnetic activity that is considered potentially dangerous and allow you to view any alerts in the app in more detail.

AuroraWatch UK provides free data for the public and allows researchers to access it for their own purposes. The data is provided by Lancaster University.
