Scientists at Aberystwyth University are spearheading a groundbreaking project to enhance the accuracy and reliability of space weather forecasting. This initiative, led by Professor Huw Morgan from the Department of Physics, aims to unlock the secrets of the Sun’s magnetic field, particularly within its outer atmosphere, the corona.
Understanding the Challenge of Space Weather Prediction
Space weather, driven by solar activity such as solar storms and eruptions, poses significant risks to modern technology. These events can disrupt satellites, power grids, and global communications systems. Currently, models of the Sun’s magnetic field rely solely on data from the Sun’s surface, leaving the corona largely a mystery. This limitation hinders the precision of space weather predictions, particularly in pinpointing the timing of disruptive solar events that affect Earth.
The CorMag Project: A New Approach
The project, titled ‘CorMag: A magnetic model of the corona with upper boundary observational constraints,’ is funded by the Science and Technology Facilities Council. It represents a novel approach to space weather forecasting by harnessing data from coronagraphs – special instruments that block out the Sun’s intense light to reveal its outer atmosphere. By studying patterns in this data, the team aims to adapt existing models and provide the scientific community and space weather forecasters with a more accurate picture of the Sun’s magnetic field.
Professor Morgan explains, “This project will harness data from coronagraphs – special instruments that block out the Sun’s intense light – to reveal the Sun’s outer atmosphere. By studying patterns in this data, we will be able to adapt existing models and offer the scientific community and space weather forecasters a more accurate picture of the Sun’s magnetic field.”
Implications for Infrastructure and Research
The enhanced maps generated by the CorMag project will significantly boost the precision of space weather predictions. This improvement has important implications not just for scientific research, but also for operational forecasting at institutions like the UK Met Office. Improved forecasting will help infrastructure operators take proactive measures to mitigate the problems caused on Earth by solar activity.

Looking Ahead
The CorMag project represents a significant step forward in our ability to predict and prepare for space weather events. By unlocking the secrets of the Sun’s corona, Aberystwyth University is contributing to a safer and more resilient technological infrastructure for the future. This research not only advances our scientific understanding but also has practical applications that can protect critical systems from the impacts of solar activity.
