The aurora borealis (or northern lights) is a spectacular natural phenomenon which can occasionally be seen in the night sky over Britain. Once seen, it is never forgotten.

This web site allows you to monitor geomagnetic activity in real time, and will let you know when aurora may be visible from the UK.

We offer a free Aurora Alert email service to warn you whenever aurora are likely to be seen across Britain. These alerts can be forwarded to your phone as a text message, so you will know when to look out for aurora wherever you are.
