Aurora Watch (UK)

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

The Aurora Borealis, or Northern Lights, is a breathtaking spectacle sometimes 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 geomagnetic activity increases, signifying a higher likelihood of aurora sightings. These alerts are triggered by changes in the AuroraWatch status level.
• Real-time Status: Check the current alert status (see Notes below).
• Recent Activity: View geomagnetic activity history for the past 24 hours.
• 30-Minute Forecast: Access a 30-minute forecast model from the Space Weather Prediction Center (SWPC).

Important Notes:

• Not a Forecasting App: AuroraWatch UK is not a prediction tool; it provides alerts based on observed geomagnetic activity.
• Phone Settings: Battery saver modes or similar settings that restrict push notifications may limit or prevent alerts. Ensure notifications are enabled for the AuroraWatch UK app in your phone's settings.
• Alert Delays: Alerts are subject to a delay to allow data stabilization, as recommended by Lancaster University. Alerts are not sent retroactively. If your phone is off or offline when a status increase occurs but returns to normal before the next data update, you will not receive an alert.
• Location Considerations: Alerts primarily use 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 (e.g., Shetland).
• App Development: This Android app is developed and maintained by Smallbouldering Projects and is not an official Lancaster University application. 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 (Updated Oct 20, 2024):

• Added abbreviations to the "About" section.
• Added Bristol and Portsmouth to the list of locations.
• Introduced a new optional alert notification triggered by specific value increases. This allows for additional notifications if, for example, the status value (nT) rises further after a red alert has already been issued.
