The Astrophysics Research Group in the UFS Department of Physics recently collaborated with the Institute of Astrophysics of Andalusia (IAA) in Spain and the University College of Dublin (UCD) in Ireland, to install a robotic telescope at the Boyden Observatory.

The Astrophysics Research Group in the Department of Physics at the University of the Free State (UFS) is part of an international collaboration with the Institute of Astrophysics of Andalusia (IAA) in Spain and the University College of Dublin (UCD) in Ireland, which focuses on measuring the brightness of transient sources. Knowledge gained from studying these cosmic X-ray sources, which seem to appear in the sky for a short time before disappearing, will lead to a more complete and better understanding of the universe, believes Prof Pieter Meintjes, Professor of Physics and Head of the Astrophysics Programme in the Department of Physics.

To facilitate these observations, a robotic telescope network has been established, with the Boyden Observatory selected as one of the sites for BOOTES 6 (a Burst Observer and Optical Transient Exploring System).

The UFS and the IAA started working on this project more than two years ago. The foundation and pier were built through a local tender, and in January 2020, part of the dome of the structure housing the telescope arrived by ship. Due to the COVID-19 pandemic there were some delays, resulting in the crew from Spain only arriving in South Africa with the telescope and hardware in November 2021, but having to return to their country without completing the installation. They returned in April, and in early May completed assembling the telescope in collaboration with UFS researchers and technicians.

Robotic telescope opportunity to further own research

The main scientific objective of the robotic telescope is to observe and monitor the optic counterparts of gamma-ray bursts as quickly as possible when detected from space or other ground-based observatories.

Prof Meintjes says they will use the telescope to observe these transient sources that goes into an eruptive phase for a short span of time. “Since BOOTES has an enormously fast slew rate, it can start observations of erupting sources within a few seconds, which allows the Astrophysics Research Group to get data very quickly. This will certainly give us an edge over other international astronomy groups that are also involved in the same type of research,” says Prof Meintjes, the local coordinator of the project who is overseeing the whole operation locally. 

He explains the importance of monitoring these packets of enormous energy. “By observing the optical afterglow of the gamma-ray bursts, we can establish its point of origin in space. Furthermore, the shape of the optical afterglow light curve gives insight into the type of mechanism behind the gamma-ray burst, i.e., whether the burst is produced by a collision between two neutron stars or by the explosion of a hypernova event.” 

The knowledge gained with research made possible by the robotic telescope will lead to a more complete and better understanding of the universe. – Prof Peter Meintjes

The UFS Astrophysics Research Group, with its research focus on high-energy astronomy and the physics behind gamma-ray bursts, has a particular interest in this project. As the local custodians of the project and in terms of a memorandum of understanding, the group is guaranteed a certain amount of telescope time for its own in-house observation programmes.

Project expands UFS’ international research footprint

Besides the opportunity for knowledge exchange, this project establishes Bloemfontein as a region where research of international quality is being done and will help to attract talented learners to the UFS. “The successful operation of the robotic telescope may also draw more international groups to bring robotic telescopes to Boyden, thus expanding our international research footprint,” he adds. 

The fact that the Boyden Observatory is in the Southern Hemisphere and has access to the galactic centre region with its host of very interesting astronomical objects and the Magellanic Clouds, makes it a very attractive site for astronomical research,” says Prof Meintjes.

“We also have a number of years of experience in robotic telescopes in the sense that we have been hosting the Watcher telescope, operated by the University College Dublin in Ireland, since 2001. Once mounted in middle May 2022, this will then be Boyden’s second robotic telescope.”

Power interruptions: Information for internal communication
2008-01-31

As part of the UFS’s commitment to address load shedding, the management would like to communicate the following:

The UFS mainly deals with the power interruptions by way of (a) the possible installation of equipment (e.g. generators) and (b) operational arrangements to ensure the functioning of the UFS in spite of power interruptions.

During the past week progress was made on both fronts. The information that follows resulted from a meeting of a task team of Physical Resources led by Mr Nico Janse van Rensburg, which took place on Monday 28 January (this task team naturally focuses on physical solutions) and a discussion by Exco on Wednesday 30 January 2008. Exco discussed the recommendations of the mentioned task team in respect of physical aspects, as well as the operational arrangements proposed by faculties.

Physical solutions

A Main Campus

1. New emergency power installations already approved:

Last week Exco gave its approval for the design and installation of emergency power equipment in all the large lecture-hall complexes to proceed immediately.

In all these cases

  • load surveys have been completed and a start has been made with the ordering of equipment and the process of appointing contractors. (Exco approved the adjustment of normal tender procedures in an attempt to expedite completion.)
  • generators with 20-30% more capacity than required for the current load are being ordered.
  • provision is being made for the connection of lights and at least one wall plug to the emergency power.
  • the expected construction time is 16 weeks (except in the case of the Flippie Groenewoud Building where it is 6 weeks).

The above-mentioned concerns lecture halls/ venues in the following buildings: Examination Centre, Flippie Groenewoud Building, Stabilis, Genmin and the Agriculture Building.

As far as the Agriculture Building is concerned, a larger generator (larger than required for lecture venues only) is being ordered in view of simultaneously providing essential research equipment (refrigerators, ovens, glasshouses) with emergency power within 16 weeks.

2. Investigation into the optimal utilisation of present emergency power installations

All the emergency power systems are being investigated on the basis of a list compiled in 2006 to determine whether excess capacity is available and whether it is possible to connect additional essential equipment or lights to it.

The electrical engineer warns as follows:
“Staff members must under no circumstances overload present emergency power points.

A typical example of this is a laboratory with 10 power points of which 2 points are emergency power outlets. Normally a fridge and freezer would, for example, be plugged into the two emergency power points, but now, with long load-shedding interruptions, a considerably larger number of appliances are being plugged into the power point by means of multi-sockets and extension cords. In the end the effect of such connections will accumulate at the emergency generator, which will then create a greater danger of it being overloaded and tripping, in other words, no emergency power will then be available.”

3. Requests and needs addressed directly to Physical Resources or reported to Exco via the line managers.

All the physical needs and requests addressed directly to Physical Resources or submitted to Exco via the line managers are being listed, classified and considered technically in view of their being discussed by the task team on Monday 11 February.
The information will (a) lead to recommendations to Exco regarding possible additional urgent emergency power installations, and (b) be used in the comprehensive investigation into the UFS’s preparedness for and management of long power interruptions.

Requests that can easily be complied with immediately and that fit into the general strategy will indeed be dealt with as soon as possible.

4. Purchase of loose-standing equipment: light, small, loose-standing generators, UPSs as solutions to/ aids during power interruptions

Exco approved that

a) faculties and support services accept responsibility themselves for the funding and purchase of loose equipment such as, for example battery lights, should they regard these as essential.
b) UPSs (uninterruptible power supplies) that faculties and support services wish to purchase to combat the detrimental effect of unexpected power interruptions on computer equipment) can (as at present) be purchased from own funds via Computer Services.
c) UPSs (uninterruptible power supplies) that faculties and support services wish to purchase to combat the detrimental effect of unexpected power interruptions on other types of equipment can normally be purchased from own funds with the consent of the line manager concerned.
Note: Please just make sure of the appropriateness of the equipment for a specific situation: it is not a power supply that can bridge a two-hour power interruption.)
d) small, loose-standing generators can be purchased from own funds via Physical Resources and installed under their supervision.
e) laptop computers can , where necessary, be purchased from own budgets. The availability of second-hand laptop computers must be taken into account.

B Vista

No major problems have been reported to date. The situation is being monitored and will be managed according to need. The same guidelines that apply to the Main Campus will naturally also apply to the Vista Campus.

C Qwaqwa

The situation is receiving attentions and solutions have already been found for most problems.

D General

1. All-inclusive project
A comprehensive investigation into the UFS’s preparedness for and management of long power interruptions will be launched as soon as possible. Available capacity will be utilised first to alleviate the immediate need. The needs assessment to which all faculties and support services have already contributed is already an important building block of the larger project.

2. Building and construction projects currently in the planning and implementation phase
The need for emergency power for projects such as the new Computer Laboratory is being investigated proactively and will be addressed in a suitable manner.

3. Liaison with Centlec
Attempts at direct and continuous liaison are continuing in an attempt to accommodate the unique needs of the UFS.

4. HESA meeting and liaison with other universities
A representative of the UFS will attend a meeting of all higher education institutions on 11 February. The meeting is being arranged by HESA (Higher Education South Africa) to discuss the implications for the sector, the management of risks and the sector’s response to government.

5. Internal communication
It is the intention to communicate internally after every meeting of the task team, which will take place on Mondays. Strategic Communication will assist in this regard.
