In his book, The World is Flat, Thomas Friedman mentions how at first countries, then companies, and eventually communities went global. In true flat-world fashion, a combined team of the University of the Free State (UFS) and the Astronomical Society of South Africa – led by Prof Matie Hoffman, Associate Professor in the Department of Physics – participated in a once-in-a-lifetime event with their counterparts from the Ellinogermaniki Agogi School and the Skinakas Observatory in Greece.

On 21 December 2020, Earth was treated to the Jupiter-Saturn conjunction, when the two planets were only 0.1 degrees apart in the sky. Although conjunctions are regular phenomena, NASA mentions that the great conjunction of Jupiter and Saturn in 2020 was the closest since 1623 and the closest observable since 1226! A pinkie finger at arm’s length could cover both planets – although they were still millions of kilometres apart in space.

Planning started months ahead of the event, with the Ellinogermaniki Agogi Observatory in Greece and the Boyden Observatory in Bloemfontein chosen as the two selected vantage points. From both the Southern and Northern Hemisphere, the conjunction would be broadcast live on YouTube. As with any other technical project on an international scale, challenges arose. For example, in the Northern Hemisphere, it was already dark at 17:45 while the South African astronomers were still basking in sunlight until after 19:00. The conjunction would only be visible from South Africa after 19:30, almost two hours after it would be visible in Athens. The time was well used, with the event including a word of welcome by the Consul General of Greece in South Africa, Ioannis Chatzantonakis, presentations on Saturn and Jupiter, as well as a virtual tour of the Boyden Observatory, emphasising its connection with Greece through its first Director, Stefanos Paraskevopoulos. 

On Saturday, 19 December, the teams ‘gathered’ on opposite sides of planet Earth to do a dry run. One could sense the urgency and tension as both teams realised that they would have a huge captive audience on YouTube, and plans had to be made in case of connectivity challenges and if the weather did not allow the conjunction. As preparations progressed, Prof Hoffman was talking to his Greek counterparts and was simultaneously walking around with his laptop to share the landscape and activities via his webcam with colleagues in Greece. 

Monday 21 December 2020 – the weather prediction was correct. Clouds covered the Free State sky and scattered raindrops started to fall. Revert to Plan B. A recording made on Saturday evening was shared via the YouTube link, while a live feed of the conjunction from elsewhere in South Africa was arranged. From both sides of the world, information was shared about the history of the venues, as well as the marvel of what was happening in space. Fortunately, expert planetary photographer Clyde Foster was able to share a live feed just after 19:30 from the observatory at his home in Centurion, Gauteng. Those attending the event where visuals and speakers were together on one screen – yet thousands of kilometres apart – watching an event in outer space, will indeed agree with Thomas Friedman: the world is flat. The live-stream event of the conjunction was a catalyst that will result in continued collaboration between the UFS and colleagues in Greece in the field of astronomy. 

By the time of this writing, the livestream has reached more than 50 000 people.

The Council of the University of the Free State (UFS) elected Mr Willem Louw as the new Chairperson during a special meeting on Friday 20 January 2017. He was Vice-Chairperson of the Council since 13 March 2015. Dr Nthabeleng Rammile was elected Vice-Chairperson at the same meeting, making her the first woman in the history of the university elected to this position.

The election of Mr Louw comes after the announcement by Justice Ian van der Merwe at a Council meeting on 2 December 2016 that he will be stepping down as Chairperson on 31 December 2016.

Mr Louw has served on the Council since 11 September 2009 and was elected as member of the Executive Committee of the Council on 18 November 2011. He furthermore serves on the Council’s subcommittees for Audit and Risk Management, and Honorary Degrees.

In accepting his election as Chairperson, Mr Louw said that he appreciates the trust Council has bestowed on him. “It is a privilege and honour to lead Council and I look forward to the challenge. With the support of Dr Rammile and the rest of the Council, I endeavour to ensure that the university management is assisted in the governance of the university and that the Council plays its governance role fully at all times,” he said.

“The UFS is privileged to have Mr Louw and Dr Rammile leading its Council at such a crucial time in the South African higher-education sector. Their combined experience will be of great benefit to the university community,” said Prof Nicky Morgan, Acting Vice-Chancellor and Rector of the UFS.

Mr Louw is an Associate of the Transnet Centre for Business Management of Projects at the University of Stellenbosch Business School and a non-executive Director of Group Five Limited. He was previously Managing Director of the technology business unit and a member of Group Management at Sasol, where he worked from 1985 until 2011. He is a member of the South African Council for the Project and Construction Management Professions and a Fellow of the South African Academy of Engineering. Mr Louw received his Bachelor’s and Master’s degrees in Civil Engineering from Stellenbosch University and his MDP (Management Development Programme in Project Management) from UNISA. He is currently enrolled for a PhD in Business Management and Administration at the University of Stellenbosch Business School.

Dr Rammile has served on the Council as representative of the religious communities since 1 January 2016. She is also member of the Council subcommittees for Audit and Risk Management, and Naming. She obtained a PhD in Brand Management at the UFS, where she also lectured in the Department of Business Management from 2003 to 2014. She is a pastor at Global Reconciliation, where she is responsible for women’s ministry, community outreach projects, and multimedia.

Mr Louw will serve as Chairperson of Council until 31 December 2018, and Dr Rammile will serve as Vice-Chairperson until 12 March 2018.
