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.

Student rights revived

2015-03-30

Lindokuhle Ntuli fulfils his promises.

“I can assure you that each and every promise that I’ve made to the students will be fulfilled.”

That is a promise that Lindokuhle Ntuli, SRC Legal and Constitutional Affairs (Bloemfontein Campus) gave to Kovsie students. The fourth-year LLB student and founder of the UFS Legal Behemoth describes himself as an ambitious person with a passion for law, order, and formality.

He explains the duties of his portfolio as “the office that will really ensure that the interests of all students are catered for. That student’s consumer rights are respected and not violated.” Through his portfolio, he aims to make sure that students are aware of what their rights are.

As part of his portfolio, Ntuli has re-introduced the Student Court, which will be fully functional during the second semester. The portfolio also introduced the Student Engagement Forum. The purpose of the forum is for students to share their grievances with regards to student rights violations. These discussions will take place twice a semester.

“The student engagement forum is the means by which we are able to really assess what kind of rights of the students are being violated,” Ntuli added.

Together with Louzanne Coetzee, SRC Accessibility and Student Support, Ntuli aims to establish the Student Rights Desk. The desk will deal directly with student rights on campus without recourse to the student court or external courts.

When asked about what his vision for the SRC is, Ntuli responded:

“My vision for the SRC is to see the SRC really attending to each and every need of students. We must advocate for students in the best way we can.”

And the words Lindokuhle lives by?

“Law and order exist for the purpose of establishing justice, and when they fail in this purpose, they become the dangerously structured dams that block the flow of progress” (Martin Luther King Jnr).
