Geomagnetic Disturbance Alert

27th March 2017

British Geological Survey

There is an increased chance of viewing the aurora in the next 24-48 hours due to the effects of a high speed stream from a large coronal hole.

The solar wind speed started increasing this morning and we have already observed geomagnetic storm conditions today. As the solar wind speed appears to still be increasing, further storm conditions are possible tonight and tomorrow. 

Assuming clear dark skies, and a continuation of geomagnetic storming, there is an increased chance of seeing the aurora. In the UK, those in Scotland, northern England and Northern Ireland may have the best opportunities.
