Hungarian Researchers Advance Space Weather Forecasting for Safer Satellites
A significant development from the HUN-REN Institute of Earth Physics and Space Science (EPSS) in Sopron, Hungary, promises to revolutionize space weather forecasting, thereby enhancing the protection of satellites and Earth-based infrastructure. The HUN-REN Hungarian Research Network reports that this project will significantly improve the prediction of extreme space weather events, providing invaluable support for stakeholders in the space industry.
The European Space Agency (ESA) meticulously monitors space weather conditions to ensure the safe operation of satellites. Researchers from the HUN-REN FI have contributed to this effort by developing new space weather data products that enhance situational awareness in Earth’s near-space environment. By refining these predictions, the Hungarian team aims to mitigate the risks posed by space weather to satellite operations and critical technologies such as GPS navigation, telecommunications, and internet services. In the U.S., this is particularly relevant given the dependence on these technologies for everyday activities, from navigation apps to financial transactions.
Space weather encompasses the dynamic processes that occur in the space surrounding Earth, primarily driven by solar activity. During periods of heightened solar activity, extreme fluctuations can take place over short periods, endangering satellites and the technologies that rely on them. These conditions can disrupt GPS signals, affect communication systems, and even cause failures in power grids, as seen in the 1989 geomagnetic storm that caused widespread blackouts in Canada and the northeastern United States.
‘With these measurements, we can better understand space weather processes, enhance their predictability, and create a safer environment for space industry players,’ researcher Tamás Bozóki of HUN-REN FI explained. “Such advancements are crucial for ensuring the reliability of satellite communications, which are essential for emergency services, military operations, and commercial aviation in the U.S.
“The HUN-REN Institute became the first institution in the region to join ESA’s Swarm DISC (Data Innovation and Science Cluster) consortium in autumn 2022. The Swarm satellite mission is dedicated to analyzing Earth’s magnetic field, and the Hungarian researchers are working to comprehend the underlying mechanisms behind extreme space weather events. Their insights contribute to enhanced forecasting models and help satellite operators prepare for high-radiation events by developing emergency protocols or designing more resilient spacecraft.
One pivotal aspect of their research is the examination of ultra-low frequency (ULF) waves, which are instrumental in energizing high-energy particles that pose risks to satellites. The team has formulated advanced algorithms capable of reliably detecting and characterizing these waves. It has been found that their occurrence is closely linked to the movements of the plasmasphere, a cold plasma region enveloping Earth.
‘We found that the location of these waves strongly follows the motion of the plasmasphere’s outer boundary. This suggests that the plasmasphere’s dynamics play a fundamental role in the generation and propagation of these waves, Ó Senior Researcher Tamás Bozóki
elaborated.

The data products and associated documentation developed by the Hungarian researchers are now freely accessible on ESA’s dedicated platform. Their initial research paper detailing these discoveries has been published in the
Journal of Geophysical Research: Space Physics

The HUN-REN EPSS team is on the verge of ESA’s upcoming NanoMagSat and SMILE missions, which will further propel the advancement of space weather monitoring. The SMILE mission, a joint endeavor between China and Europe, will scrutinize how the magnetosphere and ionosphere react to geomagnetic storms and substorms through in-situ measurements and newly developed remote-sensing imaging techniques.
According to Deputy Director for Space Research at HUN-REN EPSS Balázs Heilig, Hungarian scientists will contribute by analyzing Swarm and NanoMagSat data, together with ground-based observations, to enhance comprehension of substorm formation, development, and impact.
As space weather forecasting continues to evolve, the pioneering research undertaken by Hungarian scientists is playing a crucial role in fortifying global space infrastructure against solar-induced disturbances. Their contributions ensure that forthcoming satellite missions can operate more safely and efficiently, even under extreme space conditions. This is particularly important in the context of global technological dependence, where disruptions from space weather events can have far-reaching consequences.
The space weather initiative touted by Hungarian scientists mirrors similar efforts in the U.S., where organizations like NOAA and NASA work in tandem to advance space weather monitoring. The collaborative efforts between international research bodies and space agencies illustrate a global commitment to understanding and mitigating the risks posed by space weather.
Despite these advancements, some administrators have counterarguments, suggesting that the cost of developing and implementing such sophisticated monitoring systems may outweigh the benefits. However, the potential savings from preventing space weather-induced disruptions—such as avoiding widespread power outages or satellite malfunctions—can far outweigh the initial investment
. There are also arguments about the feasibility of protecting all satellites from space weather events. Given the vast number of satellites orbiting Earth, it is impractical to ensure every satellite’s resilience. Nevertheless, the research from HUN-REN marks a significant step forward in identifying the most critical vulnerabilities within the space environment and mitigating their consequences.
