Geomagnetic Disturbance Alert

Geomagnetic Disturbance Alert

29th March 2022

British Geological Survey


Assuming clear dark skies, there is an increased chance of seeing the aurora on 31st March and April 1st. In the UK, those in Scotland, northern England and Northern Ireland may have the best opportunities.

This is due to the expected disturbance in the Earth’s magnetic environment as a result of two Earth-directed Coronal Mass Ejections or CMEs. Both CMEs are associated with M-class flares, with the first lifting from the Sun at around 11:30UT on 28th March and the second following approximately 8 hours later, at 19:20UT. These CMEs are expected to arrive at Earth early on 31st March, causing significant disturbances to the geomagnetic field.
