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.

New SRC constitution for UFS main campus agreed upon by all organisations

2005-07-20

University of the Free State Fact Sheet

1. The Council of the University of the Free State (UFS) unanimously approved an amendment to the SRC constitution for the main campus to allow for the introduction of proportional representation (PR) alongside a first-past-the-post electoral system.

2. This decision was taken by the UFS Council on 10 June 2005 at the same meeting where it also approved the establishment of a Central SRC for the three campuses of the UFS.

3. The new main campus SRC constitution is the result of consensus reached during a lengthy negotiation process involving diverse student formations such as Sasco, the ANC Youth League, the Young Communist League, the ACDP, HEREXVII, KovsieAlliance, as well as the democratically elected SRC members of the main campus. Independent persons such as Mr Jack Klaas and Mr Kobus van Loggerenberg facilitated the negotiation process.

4. The consensus reached during this process, and the subsequent decision by Council, represent a major breakthrough for student governance and transformation of the UFS main campus and constitutes a legitimate basis for the democratic participation of all students at the UFS main campus in the governance of the university.

5. The introduction of the proportional representation system follows earlier calls by some student formations, notably Sasco and the ANC Youth League, for such a system to be introduced at the UFS main campus in Bloemfontein.

6. In terms of the amendments to the main campus SRC constitution, nine of the 18 SRC members are to elected by means of proportional representation and nine on the basis of an direct, first-past-the-post election.

7. The following portfolios of the main campus SRC will be contested by individual candidates on the basis of “first past the post”:
• president
• secretary
• academic affairs
• legal and constitutional affairs
• student development
• arts and culture
• men’s internal liaison
• ladies internal liaison
• media, marketing and liaison

8. The following nine portfolios will be contested by affiliated organizations on a proportional representation basis.
• two vice-presidents
• treasurer
• dialogue and associations
• transformation
• campus affairs and recreation
• sport
• international affairs
• community service

9. These two decisions regarding student governance represent a breakthrough in that, for the first time in many years, all SRC constitutional changes were processed and approved by the June meeting of the Council, well in time for the scheduled August SRC election; in addition, all relevant student organizations have been part of the process and all have accepted the outcome of the process.
