The Space Weather Observatory in Antarctica plays a crucial role in understanding the rarest, most damaging space weather events that impact on critical infrastructure such as satellites and power lines.
National capability science
The Space Weather Observatory is funded as part of PRESCIENT (UK Polar Research Expertise for Science and Society).
The Sun undergoes a periodic cycle of activity ranging from solar minimum to solar maximum over an average of 11 years. Geomagnetic storms that impact society and our technology can occur at any point during the 11-year cycle though they tend to occur more frequently close to solar maximum.
SWO will deliver sustained observations of space weather parameters, through the 2025 solar maximum and the descending phase of the solar cycle, that will support numerical modelling that informs the UK Risk Register on space weather threats. Our Antarctic network will be expanded with new instruments and greater geographic range to fill previous observational gaps
Sustained observations
Year-round observation of space weather events acquired at key sites including Halley VI,Rothera and in the deep field, to improve our understanding of the complex chain of Sun-to-Earth processes. They underpin assessment of the likely impact of severe space weather events and design of mitigation guidelines. SWO will supply high quality measurements to seven global instrument networks, levarging considerable scientific return and allow us to track the more hazardous solar maximum conditions.
Data are freely available to researchers, enabling collaborative research activities to increase our understanding of the science of space weather in a world that is becoming increasingly susceptible to this natural hazard.
Professor Richard Horne is interviewed about space weather
Our research ambition for this project is to understand how solar variations affect the Earth’s space radiation environment, upper atmosphere and climate in the Polar Regions; and to use this knowledge to inform industry and policy decision-making and provide real-time situation awareness for satellite operators. We will:
Supply high-quality measurements to seven global instrument networks, leveraging considerable scientific return
Track the more hazardous solar maximum conditions.
Provide space weather expertise and resources
Support the government Space Weather Preparedness Strategy.
A rare total solar eclipse in Antarctica this weekend (Saturday 4 December) is giving researchers a unique opportunity to learn more about how solar eclipses affect space weather. The next …
Using data to assess risk
We exploit the data collected by a suite of instruments in Antarctica to study space weather events. These are spread between the research stations at Halley and Rothera along with a number of field stations.
The Super Dual Auroral Radar Network (SuperDARN) has been operating as an international co-operative organisation for over 20 years, and has proved to be one of the most successful tools …
The MF radar measures an altitude profile of the horizontal wind in the mesosphere, between 55 and 95 km. This is the region where breaking gravity waves drive a pole-to-pole …
The riometer at Halley measures the radiowave noise at 30MHz coming from the Galaxy. Typically there is a gentle variation of the noise during each day as the Earth turns …
Search coil magnetometer Several kinds of natural waves in the ultra-low-frequency (ULF) range are generated in Earth’s space environment (the magnetosphere, bounded by Earth’s magnetic field as it extends into …
Bomem The Bomem has been operating at Halley periodically since 2002. It’s a spectrometer: an instrument that splits light into its component colours. It is designed to look specifically at …
The Halley VLF receiver listens to very-low frequency radio waves as part of a network of receivers located all over the polar regions. The data gathered by this network is used by …
