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.

UFS to implement a policy on HIV and Aids

2005-03-14

The Council of the University of the Free State (UFS) approved the implementation of a policy on HIV and AIDS.

“With this policy we recognise the seriousness of the HIV and AIDS epidemic and the potential impact this disease can have on both the UFS and the wider society. We are committed to addressing HIV and AIDS in a positive, supportive and non-discriminatory approach by providing resources and leadership to implement HIV and AIDS university-based, as well as community outreach programmes,” said Dr Ezekiel Moraka, Vice-Rector: Student Services at the UFS.

The objectives of the policy include:

The protection of individual rights of confidentiality and freedom from discrimination.
The promotion of a sustained educational programme that provides counseling and current accurate information to the University community and to the outside community.
The promotion of behaviors that reduce or minimise the risk of acquiring HIV infection and generally create a safe environment.
The provision of leadership in teaching, research and community service on HIV and AIDS and its impact.
The provision of leadership in promoting the human rights based approach to HIV and AIDS, and thereby also breaking down the stigma attached to the illness.

“The policy also makes provision for the establishment of a Centre for HIV and AIDS within Kovsie Health. This centre will render HIV and AIDS related support services and initiatives to the whole campus,” said Dr Moraka.

According to Dr Petro Basson, head of the Centre for HIV and AIDS at the UFS, there is less than 1% incidence of HIV positive cases amongst undergraduate students on the main and Vista campuses. All these students take part in a voluntary confidential counseling and testing programme (VCCT). In the case of postgraduate students, there is about 1% incidence on both campuses.

“The Centre for HIV and AIDS has led in the development of information campaigns and workshops for students and staff to make them aware of the risks of HIV and AIDS and the necessary measures to ensure their safety. We have found that, because students have access to the right information, they are more cautious when it comes to HIV and AIDS. Awareness campaigns are also conducted throughout the year – especially during rag and intervarsity,” said Dr Basson.

“Some departments have also taken the lead in introducing aspects of HIV and AIDS into academic programmes while important research on the HIV and AIDS topic has already been completed and receives continuous attention,” said Dr Basson.

To achieve a coordinated approach, a Life Skills Forum will be established consisting of representatives of among others the Student Representative Council (SRC), academic departments, trade unions, Kovsie Counseling and Development, etc.

“With this policy the UFS pledges its commitment to participate actively in the fight against the disease,” said Dr Moraka.
