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.

Graduation ceremony awaited with great excitement

2011-06-22

Everything is running according to plan on the Bloemfontein Campus of our university for the graduation ceremony of Ms Oprah Winfrey, which is taking place in the Callie Human Centre today, 24 June 2011.

The graduation ceremony, during which an Honorary Doctorate in Education will be conferred upon Ms Winfrey, promises to be something special. Measured against the smooth course of the preparations, the speed at which the tickets were obtained and the continuous interest amongst UFS staff and students, as well as members of the public, this promises to be a real 2011 highlight for all who are going to attend the event.

Strict safety and security measures shall be enforced and therefore, ticket holders are requested to make sure that they arrive early on the Bloemfontein Campus.

The UFS is aware of the fact that tickets are sold illegally at shopping centres in Bloemfontein. Computicket equipment shall be used on the premises tomorrow to ensure that only persons who have original tickets in their possession are admitted. People found to be in possession of forged tickets tomorrow shall be prosecuted.

The doors of the Callie Human Centre shall open at 13:00 on Friday for ticket holders and shall be closed strictly at 14:00. For safety and security reasons, nobody shall be allowed to enter or leave the building after the doors were closed.

Although the entrance gates to the Bloemfontein Campus shall not be closed, certain streets on the campus will be closed for some time today (23 June 2011) and the whole of Friday (24 June 2011). More information about this is available at www.ufs.ac.za

Clear signs, as well as voluntary staff, shall guide parking visitors to their parking spaces. The volunteers were selected after staff of all three campuses offered their assistance for the day.

Amongst the 4 500 guests attending the graduation ceremony are various well-known personalities and dignitaries, alumni, learners and other stakeholders of the university. Good reaction has also been received from the local, national and international media.

The programme in the Callie Human Centre is as follows:

13:00 Doors open
14:00 Doors close
14:30 Opening performances
15:30 Graduation ceremony
16:00 Ms. Winfrey’s speech and question and answer session with students
18:00 Programme ends.
