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 arts are experiencing a boom

2013-09-03

The arts at the University of the Free State are experiencing a boom, with several Kovsie artists achieving on a national platform. Dot Vermeulen, a junior lecturer in the Department of Fine Arts, is the latest UFS artist to be honoured nationally as the winner of the 2013 Sasol New Signatures art award.

The award is rewarding emerging young artists. The winning entry, entitled “Desperately disciplined,” by Vermeulen, who is currently studying toward her master’s degree in Visual Arts, was chosen from approximately 400 entries.

Earlier this year, Pauline Gutter, a former Kovsie, won the Absa L’Atelier competition, which is South Africa’s most prestigious art competition. The year before, another former student from our Department of Fine Arts, Elrie Joubert, won the competition.

Vermeulen says there are brilliant people at the UFS who are active in visual arts at various levels. "People such as Janine Allen-Spies (lecturer in painting) and Angela de Jesus (curator of the Stegmann gallery) are not only good artists, they are also involved with the community and invest a great deal of energy into the development of young artists. From my own experience, I can say that I have benefited a lot from academic scholarships from the UFS in the course of my study career."

She says her winning entry refers to the relationship between traditional tactile painting and contemporary digital media. "The focus is especially on hidden moments of absorption and correspondence during the art-making process. The painting installation depicts a reading nude figure on a couch. A computer screen is mounted on a stand in front of the painting, animating the same image, while at the same time blocking the view of the painting. In the animation, the nude figure pages through her book from time to time, with the paint and digital drawing marks moving around her. The text “Envoi is typing…” is also animated on the surface of the couch repeatedly. It is suggestive of internet chat boxes, which often pop up on the screen while I am working on my laptop."

As winner of the Sasol New Signatures art award, Vermeulen won R60 000 and the opportunity of a solo art exhibition in the Pretoria Art Museum.
