You are here:  AuroraWatch UK / Alerts

AuroraWatch UK takes geomagnetic activity measurements from AuroraWatchNet magnetometers to automatically detect when it is likely that aurora can be seen from the UK. Our colour-coded system has four levels.

ColourDescriptionMeaning
Green No significant activity Aurora is unlikey to be seen from anywhere in the UK
Yellow Minor geomagnetic activity Aurora is unlikely to be visible from the UK except perhaps the extreme north of Scotland
Amber Amber alert: possible aurora Aurora is likely to be visible from Scotland, northern England and Northern Ireland
Red Red alert: aurora likely It is likely that aurora will be visible from everywhere in the UK

We offer a number of ways to keep you informed of major events and to alert you to opportunities for seeing aurora from the UK:

Twitter

Following @aurorawatchuk on Twitter is the easiest way to stay informed. Twitter accounts are free and you may be able to have Twitter send our tweets (messages) directly to your mobile phone as SMS messages. You can also limit the times of day when tweets should go to your mobile phone. We'll automatically tweet for red and amber alerts, and also for minor geomagnetic activity. Automated tweets are limited to a maximum of 3 per 12 hours. Occasionally AuroraWatch UK administrators will also send other interesting tweets.

Twitter has a web page which describes how to receive SMS notifications. See also the list of supported mobile carriers. You are responsible for any charges that the SMS notification service may incur.

Facebook

You can follow us on Facebook. Depending upon who your mobile phone carrier is you may be able to get notifications sent to your mobile phone as SMS messages. For more information about SMS notifications see the Facebook help centre. We'll post to our Facebook wall for red and amber alerts, and also for minor geomagnetic activity. Automated posts are limited to a maximum of 3 per 12 hours.

Smartphone apps

Smartphone apps are available for Android, iOS (iPhone, iPad), and Windows Phone. They use the same data as the other alert methods but may behave slightly differently, for instance not limiting the number of alerts in a given interval.

Email

We operate an email list, this service is free of charge. Messages to this list will be infrequent but important, and will come from two sources:

We only send messages by email, but some mobile phone networks will send email notifications by SMS. For more details please consult your mobile phone provider. We are not responsible for any charges occurred from SMS notifications.
