A pioneering network of quantum sensors has been installed across the UK, offering unprecedented insights into the risks posed by space weather to national infrastructure.
Developed by the University of Strathclyde and RAL Space through the UK National Quantum Technology Programme, the five quantum magnetometers provide complete national coverage for the first time, enabling high-resolution monitoring of geomagnetic storms that can disrupt power grids, satellite navigation and transport systems.
High-resolution
They will generate high-resolution data to support the British Geological Survey (BGS) in monitoring and understanding the impact of extreme magnetic storms.
During such storms, the geomagnetic field can fluctuate with enough intensity to disrupt power grids, satellite navigation and railway signalling.
While the UK’s three established geomagnetic observatories have provided valuable national-scale monitoring, they cannot capture local variations. The newly deployed Strathclyde-built magnetometers, sited at Aberystwyth, Boulby in North Yorkshire, Blickling in Norfolk, Chilbolton Observatory in Hampshire and Thurso, are designed to address this gap.
Dr Stuart Ingleby from the Department of Physics at Strathclyde, said:
“By enabling more detailed observation of geomagnetic storms, we are improving the evidence base that informs how government, industry and society can prepare for and respond to space weather events. “
“This reflects Strathclyde’s wider role as a leader in translating quantum science into practical tools for resilience and security.”
Local impacts
Dr Ciarán Beggan, geophysicist at BGS, said: “These new measurements will greatly enhance our understanding of how extreme magnetic storms impact different parts of the country.
“This means that society in general will have access to the advice and information needed to understand where we are vulnerable to magnetic storms and to make informed decisions on how to mitigate against them.”
