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.

Rag teamwork leads to Armentum, Emily's float

2016-02-04

Perhaps the residences Armentum and Emily Hobhouse were thrown into the deep end, but they still wanted to prove a point.

This is according to Hanko Minnaar, Residence Committee member for Rag at Armentum, shortly after the residences were announced as overall float winners of the University of the Free State (UFS).

According to Minnaar, Emily Hobhouse and Armentum overcame the challenge of building a float as a two-residence team, while most of the other hostels were in teams of three.

On 30 January 2016, after about two weeks of hard work and sweat, the residence twosome was named the winner at the Bloemfontein Campus.

“I am very proud. We couldn't have asked for more,” Minnaar said, after the residences Armentum and Emily Hobhouse celebrated their victory with house songs. “Anything is possible through teamwork.”

Tom and Jerry, Olaf and a Steri Stumpie

The theme for this year was “Cartoons, Animation, and Children's Snacks”. Among other items, Armentum and Emily Hobhouse had Tom and Jerry, Olaf from Frozen, a Steri Stumpie, and a box of Astros on their float.

“We thought hard about what we wanted,” Minnaar said.

“We also asked some children, and they said that Tom and Jerry is a favourite, and Olaf has always been a winner as well. And Steri Stumpies, of course. Who doesn't like Steri Stumpies?” The residences Marjolein, Veritas, and Akasia were second overall, with Karee, Vergeet-My-Nie, and Sonnedou third.

Colourful processions

The events of the day started off with a morning procession from the Pelonomi Hospital to the Twin City Mall in Heidedal, where students and the community celebrated together, and meals were distributed.

The evening procession, from the Tempe robot in Nelson Mandela Drive to the Old Grey Sports Grounds, was greeted by hordes of spectators along the way.

Artists and Co captivate audience

In the evening, music lovers were entertained at Old Grey Sports Grounds by the legendary artists Vusi Mahlasela, the talented Karen Zoid, and an energetic Francois van Coke.

Local bands, Rise in Red and Simple Stories, added to the excitement. To top it all off, a special laser show made for a colourful visual bonus, coupled with great sound.
