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 has a contingency plan for load shedding
2008-02-13


The University of the Free State (UFS) has put in place a contingency plan to ensure that there is minimal disruption to the normal academic operations of its Main Campus in Bloemfontein whenever load shedding occurs.

The plan includes alternative arrangements for certain lectures that fall within the load-shedding schedule provided by Centlec, the emergency power generation for certain lecture halls and buildings, as well as the functioning of the UFS Sasol Library. This is in addition to emergency power equipment that has already been ordered for the larger lecture-hall complexes.

Fortunately, the Qwaqwa Campus has adequate emergency power generation capacity. The situation on the Vista Campus in Bloemfontein is being monitored, but the same guidelines will apply as on the Main Campus.

On the Main Campus in Bloemfontein the following alternative arrangements regarding the timetable for evening classes will come into effect when load shedding occurs:

  • An alternative module and venue timetable has been compiled so that classes that cannot take place on weekdays as a result of load shedding can be accommodated on Fridays and Saturdays.
  • Classes that are presented in the timeslot 18:10 to 21:00 on Thursdays are alternatively accommodated in the same venues at the same times on a Friday.
  • Classes that take place in the timeslot 20:10 to 22:00 on Wednesdays are alternatively accommodated in the timeslot 08:10 to 12:00 on Saturdays, in a few cases in different venues from those scheduled initially.
  • After consultation with students, lecturers will decide whether the alternative timetable will apply when load shedding does indeed occur or whether the alternative timetable will be a permanent arrangement.

Some other steps that have been taken regarding the functioning of lecture halls include:

  • The design and installation of emergency power equipment in all the large lecture-hall complexes within the next few months. This includes the Examination Centre, Flippie Groenewoud Building, the Stabilis and Genmin lecture halls.
  • The ordering of a larger generator for the Agriculture Building to simultaneously provide essential research equipment such as refrigerators, ovens and glasshouses with emergency power.
  • An investigation into the optimal utilisation of present emergency power installations.
    The purchasing of loose standing equipment such as battery lights, uninterruptible power supplies, loose-standing generators, etc.

The UFS Sasol Library will continue as normal as far as possible though there may be some minor changes as a result of load shedding. The library has an emergency generator that will be used in the event of load shedding to allow students and other users to exit the library. If load shedding occurs during daylight hours, the library will remain open with limited services. If the load shedding occurs after 6 pm (18:00), all users will be allowed to exit and the library will remain closed until the next day.

A comprehensive investigation into the university’s preparedness for and management of long term power interruptions is also receiving attention.
