Aurora Watch (UK)

Stay updated on Aurora Borealis sightings in the UK with AuroraWatch UK!

The aurora borealis, or Northern Lights, is a breathtaking natural spectacle occasionally visible in the UK night sky. AuroraWatch UK helps you track geomagnetic activity and receive alerts when aurora viewing may be possible.

Key Features:

• Geomagnetic Activity Alerts: Receive instant notifications when the AuroraWatch status level changes, indicating a higher likelihood of aurora sightings.
• Current Alert Status: Check the current alert level (see Notes below).
• 24-Hour History: Review geomagnetic activity over the past 24 hours.
• 30-Minute Forecast: Access a 30-minute forecast model from the Space Weather Prediction Center (SWPC).

Contact: For any issues, please email [email protected].

Important Notes:

• Not a Forecasting App: AuroraWatch UK is not a prediction tool; it provides alerts based on geomagnetic activity.
• Phone Settings: Battery saver mode or similar settings that limit push notifications may affect alert delivery. Ensure AuroraWatch UK notifications are enabled in your phone's settings.
• No Historical Alerts: The app doesn't send retroactive alerts. Alerts are only sent when the status increases and remains high enough until the next data update. A delay exists to allow data stabilization, as recommended by Lancaster University.
• Alert Location Bias: Alerts primarily utilize data from the Lancaster magnetometer. While other magnetometers exist (including one in Shetland), the Lancaster data is prioritized. This means alerts might be more conservative for those in England compared to those further north in the UK.
• Third-Party App: This Android app is developed and maintained by Smallbouldering Projects and is not officially affiliated with Lancaster University. Alert data is provided by Lancaster University using SAMNET and/or AuroraWatchNet magnetometer networks. Learn more: http://aurorawatch.lancs.ac.uk/introduction

Version 1.97 (Oct 20, 2024):
