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 cracks down on crime on campus

2006-03-15

A comprehensive plan to step up the security on the Main Campus of the University of the Free State (UFS) in Bloemfontein, was approved by the Executive Management (EM) this week.

“The plan briefly comprises of the introduction of reasonable and affordable measures that will promote a safe campus and working environment,” said Rev Kiepie Jaftha, Chief Director: Community Service at the UFS.

“With the plan we want to try and create a user friendly, but safe campus,” said Rev Jaftha.

The plan is the result of an intensive investigation about campus security done by an EM task team.

The following measures will be implemented immediately in phases:

The five current vehicle entrances and exits will remain (i.e. the gate at Nelson Mandela Avenue, the gate at Roosmaryn, the gate at Agriculture, the Wynand Mouton Avenue gate and the Furstenburg Road gate).

The number of smaller pedestrian gates will be reduced and security at those remaining will be increased.
The fences around the campus will remain, upgraded and patrolled on a daily basis.

The security measures at high risk areas (e.g. the Kovsie Church) will be stepped up and the fences in these areas will be electrified.

Vehicle exit control will be stepped up at the gates by means of a mixture of electronic and compulsory visual security control.

Public areas, streets and footpaths will be patrolled and shrubs and trees will be cut and pruned. The streets, footpaths and buildings will also be lit.

Speed reducing mechanisms will be implemented before and after the security control points at all the gates.
Additional staff will be appointed to facilitate the flow of traffic at the gates.

“Over and above these measures, the EM also approved in principle the installation of electronic equipment at all the entrance gates. This will include the installation of cameras,” said Rev Jaftha.

According to Rev Jaftha the installation of the electronic equipment will be complemented by the compulsory cutting and restarting of engines for all vehicles exiting the gates. The measure has been in force since 1 February 2006.

Last year special measures were put in place to safeguard residences and their inhabitants when security guards were placed at all the ladies residences. These measures will stay in force.

“Regular audits will be done to determine the effectiveness of the strategies and systems. Although crime in and around the campus grounds can never be completely eradicated, we want to strive to create an environment on campus and in the workplace where it can be limited,” he said.
