Stable atmospheric environments and near perfect weather conditions were the main reasons for the establishment of the Boyden Observatory a few kilometres outside Bloemfontein. This astronomical research observatory and science education centre is managed by the Department of Physics at the University of the Free State (UFS).

With the newly acquired astronomical spectrograph for the Boyden Observatory 1,5-m telescope, scientists will be able to gain visual access to both the Northern and Southern Hemisphere skies.

Collaboration with expert in stellar spectroscopy 


The spectrograph, mainly developed and built by Dr Richard Gray, will be used collaboratively for astronomical research by the UFS and the Appalachian State University (ASU) in North Carolina, where Dr Gray is based. 

Dr Gray is a world-renowned expert in stellar spectroscopy and leading author of one of the most influential textbooks on stellar spectroscopy, Stellar Spectral Classification, with co-author Christopher J Corbally.

Dr Gray recently received a Fulbright Scholarship from the Fulbright Foundation to spend a full year in the UFS Department of Physics, where he will lecture several Astronomy classes and do research in collaboration with personnel of the UFS Astrophysics Research Group. He will also lead the assembly of the instrument over the next few weeks, working with personnel and students in the Department of Physics as well as the UFS Instrumentation Division.

According to Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, some components of the instrument have been developed and constructed by the university’s Instrumentation Division, with key components purchased from funding by the Directorate: Research Development at the UFS.

Unique capability in infrastructure 

“The availability of a sophisticated instrument of this nature on the 1,5-m telescope will place the UFS Astrophysics Group in an elite bracket in terms of the available infrastructure for astronomical research,” said Prof Meintjes.

He explained: “The combined polarimetric-spectroscopic capability in one single instrument is unique. Combined with the fact that it is hosted on a research instrument that is utilised and maintained exclusively by the UFS Astronomy Group in the Department of Physics, gives this group a competitive edge in relation to most international astronomy groups.” 

The instrument is valued at close to R1,5 million.

According to Prof Meintjes, the instrument will be mounted at the backend of the UFS Boyden 1,5-m telescope and will allow them to do simultaneous polarimetry and spectroscopy of astronomical sources. “This is vital for the research we are working on,” he said.

International collaboration and student development

The instrument also brings with it the possibility of forging international collaborations for research as well as student development. “This can advance the stature of the UFS as an internationally respected research-led tertiary institution,” said Prof Meintjes. 

The possibility of making the UFS Boyden 1,5-m telescope completely remote-controlled, is being investigated. “This will serve the observational needs of researchers from both the UFS and the ASU, with researchers at ASU able to access the telescope for their own in-house research programmes. The availability of such an instrument on the UFS 1,5-m telescope also opens up the possibility to accommodate visiting researchers from ASU or elsewhere in the world at Boyden,” said Prof Meintjes.

Space-based information plays vital role in disaster-risk reduction
2017-02-28

Africa is one of the continents most affected by disasters triggered by natural hazards. The result of climate change is a reality that affects every human being, whether it is extreme heat waves, cyclones, or the devastation of drought and floods. Climate change can provoke injuries or fatalities and affects the livelihoods of people in both rural communities and urban areas. It triggers damage and losses in various sectors of development, such as housing, road infrastructure, agriculture, health, education, telecommunications, energy, and affects routine economic processes leading to economic losses.

According to Dr Dumitru Dorin Prunariu, President of the Association of Space Explorers Europe, space programmes have become an important force defining challenges of the 21st century. “Space observation is essential for climate-change monitoring,” he said.

Dr Prunariu was the keynote speaker at a two-day symposium on climate resilience and water that was hosted by the Disaster Management Training and Education Centre for Africa (DiMTEC), at the University of the Free State (UFS). He participated in the Soviet Union’s Intercosmos programme and completed an eight day-mission on board Soyuz 40 and the Salyut 6 space laboratory, where he and fellow cosmonaut Leonid Popov completed scientific experiments in the fields of astrophysics, space radiation, space technology, space medicine, and biology. He is the 103rd human being to have travelled to outer space.

The focus of Dr Prunariu’s lecture was: Space activities in support of climate change mitigation and climate resilience.

Space-based information, an extra eye that can detect a way out during disasters
“For governments to support communities affected by any disaster, precise and up-to-date information on its impacts is essential as a way to respond in a timely and effective way,” said Dr Prunariu.

Space-based information (derived using Earth observation, global navigation satellite systems, and satellite communications) can play a vital role in supporting disaster-risk reduction, response, and recovery efforts, by providing accurate and timely information to decision-makers.

“With space-based information, disaster management teams will be able to take note of recently established roads that may not appear in typical maps produced by National Geographic Institutes, but which could be used as emergency evacuation routes or as roads to deliver humanitarian assistance to those who require it in remote areas."

Space-based tools help decision-makers to improve planning
“Space-based tools and spatial data infrastructure is also crucial for policy planners and decision-makers in increasing the resilience of human settlements. Using geographic data and information collected before the occurrence of major disasters in combination with post-disaster data could yield important ideas for improved urban planning, especially in disaster-prone areas and highly-populated regions.

“In the recovery process, information on impact is used by governments to provide assistance to those affected, to plan the reconstruction process, and to restore the livelihoods of those affected,” said Dr Prunariu.

“Space observation is
essential for climate-
change monitoring.”

The symposium was attended by representatives from Liberia, Nigeria, Kenya, Ghana, Namibia, and Zimbabwe, with various international scientists from Europe imparting their expert knowledge on water and global resilience. The presence of these international experts strengthened global networks.
