🚨 Aurora alert! 🚨
A geomagnetic storm is expected over the next 48 hours due to the expected arrival of a coronal mass ejection that left the Sun on 18th January.

The fast (~1400 km/s) CME that launched yesterday is forecast to arrive sometime Tues. Probably during the day in the UK, so not great for aurora. But there's a fast solar wind stream near Earth, and the precise location/timing of that could really change the CME propagation.

Geologists at BGS have completed a major update to the geological map of the Yorkshire Wolds that will help to improve regional understanding of both the aquifer and the groundwater resources, and may assist in reducing risks to specific water supply assets.

Seismologists at BGS have published data on the number of seismic events over the past 12 months. With over 300 earthquakes recorded, data shows 2025 was an above average year for earthquakes across the UK.

‘Three norths’ set to leave England and not return for hundreds of years 🧭
The historic alignment of true, magnetic, and grid north is set to leave England, three years after they combined in the country for the first time since records began.

We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.
Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

A weak spot in the Earth’s magnetic field has nearly doubled in surface area since 2014.
BGS Geophysicist Ciarán Beggan appeared on @earthskyscience.bsky.social's podcast to explain why this is happening, and what the consequences might be.

Five new sensors being installed across the UK will provide full national coverage of the magnetic field for the first time.
The quantum magnetometer sensors will improve our understanding of extreme magnetic storms and associated effects on national infrastructure.

New highly sensitive quantum magnetometers are being installed across the UK.
These instruments are helping us understand the effects that extreme magnetic storms have on technology and national infrastructure.
