Earth directed CME on its way!

Geomagnetic Disturbance Alert

3rd November 2021

British Geological Survey

An Earth-directed coronal mass ejection was launched from the Sun early on Tuesday 3rd November. This is expected to arrive at Earth within the next 24 hours. A geomagnetic STORM is possible as a result.

Assuming clear dark skies, 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.
