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.

‘Captivating, powerful’ exhibition debuts at UFS

Sue Williamson, What is this thing called freedom?, 2016 (two-channel video, 19min 25s)

A new exhibition by internationally-recognised artist, Sue Williamson, entitled No More Fairytales, was launched in the Johannes Stegmann Gallery on the Bloemfontein Campus of the University of the Free State (UFS) on 18 August 2016. The exhibition takes the audience on an exploration into the long-term effects of South Africa’s violent past.

No More Fairytales features two new video works. In It’s a pleasure to meet you, Candice Mama and Siyah Mgoduka—whose fathers were killed by Eugene de Kock—talk about living with loss, holding, on, and letting go. The other video, What is this thing called freedom?, draws the audience into a conversation between three generations of women in the Siwani family, who talk about the humiliations of apartheid, student unrest in the 1980s, and the recent #FeesMustFall protests.

“It’s all about opening up conversations.”

Both of these works have already been invited to participate in international exhibitions, the first of which, Un Autre Continent, opens in Le Havre, France, in September 2016. The videos will appear in 2017 in Without Drums and Trumpets—100 Years of War, also in France. The exhibition will run until 16 September 2016 at the UFS.

Sue Williamson, It's a pleasure to meet you, 2016 (two-channel video, 25min)

“There is such an energy to this large piece of work; there is something captivating, something powerful about its vibrancy,” said Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness and Reconciliation Studies at the UFS. The series was commissioned by Prof Gobodo-Madikizela as part of the project, ‘Trauma, Memory and Representations of the Past: Transforming Scholarship in the Humanities and the Arts’. The five-year research project is funded by the Andrew W. Mellon Foundation through a grant of R10 million.

The launch of the exhibition was followed the next morning by an insightful dialogue session between Prof Gobodo-Madikizela, Mama, Mgoduka, Williamson, and the audience. “It’s all about opening up conversations and trying to bring out things that have been so painful and so hurtful in this country,” Williamson said.
