Space Weather Alerts

We examine solar activity daily and forecast if this is likely to have any geomagnetic effect on Earth.

If this 'space weather' indicates that a large magnetic storm is possible in the next few days we may send out a space weather alert.

You can keep an eye on the current geomagnetic activity levels for yourself.


You can sign-up to receive a Geomagnetic Disturbance Alert email or follow us on Twitter to get daily space weather forecasts or occasional aurora alerts.

Report an aurora sighting

GeoSocial logo.


We love to hear about your aurora sightings and now you can share them with everyone! GeoSocial - Aurora is a new a web mapping tool that searches for tweets related to aurora sightings and locates them as markers on a map. Currently you need a Twitter account to view the map or share a sighting but we hope to develop this to widen it's scope in the future.

If you want to report an event, tweet the hashtag #BGSaurora, the event's location (postcode: loc[EH9 3LA], town name: loc[Edinburgh], or geotag your tweet using the tweet location feature), and comments or pictures.
