There are high costs and high risks associated with the consequences of space weather events, as insurance companies recognise.
Intense space weather events are triggered by the explosive release of energy stored in the Sun’s magnetic field.
A strong burst of electromagnetic energy reaches the Earth with the potential to disrupt many of our fundamental services, such as satellite and aviation operations, navigation, and electricity power grids. Telecommunications and information technology are likewise vulnerable to space weather.
Research by the Radio and Space Plasma Physics Group in the University of Leicester’s Department of Physics and Astronomy helps our understanding of coupling processes between the solar wind and the Earth’s magnetosphere by allowing the observation of the consequences of space weather with an unprecedented resolution.
Postgraduate researcher James Borderick explained: “We introduce the importance of utilising ground-based measurements of the near space environment in conjunction with spacecraft observations and then proceed to explain the direct influences of space weather on our own technological systems.
“Utilising our new radar modes and an international array of ground-based and space-based instruments, we are ever increasing our understanding of the countless phenomena associated with the solar-terrestrial interaction.”
“One day this may lead us to the accurate predictions of the occurrence and consequences of phenomena such as Coronal Mass Ejections (CMEs), and perhaps an active defence.”
The use of ground-based radars for observations of ionospheric and magnetospheric dynamics is well established. The Super Dual Auroral Radar Network (SuperDARN) consists of networks of High-Frequency radars surrounding the northern and southern poles, which have yielded extensive data on our near space environment.
A new “double pulse” pulse sequence has been implemented on the Radio Space Plasma Physics Group’s Co-operative UK Twin Located Auroral Sounding System (CUTLASS) radars. CUTLASS forms part of SuperDARN.
The new sounding mode enhances the temporal resolution of observations of plasma irregularities within the ionosphere. It increases the cadence of pulse transmissions within the same transmission time as the standard SuperDARN-operating mode.
As an undergraduate physicist at the University of Leicester, he was awarded both the Philips and Departmental Prizes in Physics and achieved the highest mark of all 4th year undergraduates in his final year. Between his penultimate and final years, he obtained a position on the prestigious SURE research programme where he conducted a preliminary investigation on the coupling processes between the Solar Wind and the Earth’s magnetic field. He has just recently presented his Double Pulse findings at the SuperDARN Conference of 2008 in New South Wales, Australia. In the future, he hopes to continue in academia, forwarding science and simultaneously enthusing the next generation of scientists.
The research is being presented to the public at the University of Leicester on Thursday 26th June. The Festival of Postgraduate Research introduces employers and the public to the next generation of innovators and cutting-edge researchers, and gives postgraduate researchers the opportunity to explain the real world implications of their research to a wide ranging audience.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
