BOOTES-6 Telescope Station captures rare southern lights and advances UFS space research

The northern lights, with their vibrant displays of green, pink, and violet hues, have become a famous attraction in Nordic countries. But in early October, a rare sighting of the southern lights – or aurora australis – was reported in South Africa, surprising many.

Prof Pieter Meintjes, Professor in the Department of Physics at the University of the Free State (UFS), explains that both the northern and southern lights are the result of charged particles from coronal mass ejections (CMEs) on the sun, which are captured by Earth’s magnetic field. "The interaction between magnetic fields and charged particles, such as protons and electrons, is very interesting. The magnetic field forces these particles to spiral around the field lines, ultimately guiding them towards the magnetic poles. As these particles enter Earth’s atmosphere, they collide with atmospheric atoms, causing a beautiful glow. The colours of the aurora indicate which atoms are involved. Typically, hydrogen shines red, while oxygen and nitrogen produce a greenish-blue tinge," he says.

Observing the southern lights

When the display occurs above the northern magnetic pole, it is called the aurora borealis (northern lights) and can typically be observed over regions such as Alaska, Greenland, and the Nordic countries. Above the southern magnetic pole, it is known as aurora australis (southern lights), usually visible over places such as Antarctica and New Zealand. “In extreme cases – when gigantic mass ejections occurred – it can also be observed in mid-latitudes such as South Africa,” says Prof Meintjes.

This recent and rare South African sighting was also captured by the BOOTES-6 telescope station at Boyden Observatory, located just outside Bloemfontein. According to Prof Meintjes, the telescope station has an all-sky monitor – a camera constantly watching the sky for changes and monitoring, among others, cloud cover to ensure that the telescope is always safe from weather. While the monitor was taking photos of the night sky, Prof Alberto Castro-Tirado, a research professor at the Institute of Astrophysics of Andalusia in Spain, picked up the aurora.

The Institute of Astrophysics of Andalusia in Spain, in collaboration with the University College Dublin (UCD), is partnering with the UFS in a research-driven initiative involving the BOOTES-6 telescope station, installed in 2022 during the COVID-19 pandemic. Under a Memorandum of Understanding that was recently renewed for another five years, the UFS and UCD share approximately 30% of the telescope's observing time dedicated to UFS research.

“The DPRT telescope (Dolores Pérez-Ramírez telescope), named after a Spanish astronomer and lecturer at the University of Jaén, contributes significantly to our research, with publications resulting from contributions made by the telescope station and collaborators on gamma-ray bursts, occultations, and transient events co-authored by me and a colleague in the department, Dr Hendrik van Heerden,” notes Prof Meintjes.

Research-driven initiatives

Data from the telescope station is also used for their in-house projects and contributes significantly to the work of their PhD students that will be submitted in the next few years. This includes the PhD work of Helene Szegedi, who uses data from the BOOTES-6 telescope station to study cataclysmic variable systems – compact binaries that erupt regularly. Another PhD student, Joleen Barnard, studies blazar variability under the guidance of Prof Brian van Soelen. Blazars, explains Prof Meintjes, are the core of distant galaxies powered by supermassive black holes. These cosmic jets are pointed towards Earth, but fortunately, they are millions or billions of light years away; otherwise, their impact would be devastating to life on Earth.

UFS staff get salary increase of at least 7,25%

2007-11-20

During the signing of the UFS's salary agreement were, from the left: Mr Olehile Moeng (Chairperson of NEHAWU), Prof. Frederick Fourie (Rector and Vice-Chancellor of the UFS), and Prof. Johan Grobbelaar (Chairperson of UVPERSU and spokesperson of the Joint Union Forum).

UFS staff get salary increase of at least 7,25%

The University of the Free State’s (UFS) management and trade unions have agreed on an increase of 9,32% in the service benefits of staff for 2008. This includes a general minimum salary increase of 7,25%.

A once-off non-pensionable bonus of R3 000 will be paid in December 2007.

The agreement was signed today by representatives of the UFS management and the trade unions, UVPERSU and NEHAWU.

“As the state subsidy level is unfortunately not yet known, remuneration could vary several percentage points between a window of 7,25 and 8,39%,” said Prof. Frederick Fourie, Rector and Vice-Chancellor of the UFS.

Should the government subsidy be such that the increase falls outside the window of 8,39%, the parties will negotiate again.

The bonus will be paid to staff members who were employed by the UFS on UFS conditions of service on 14 November 2007 and who assumed duties before 1 October 2007.

The bonus is payable in December 2007 in recognition of the role played by staff during the year to promote the UFS as a university of excellence and as confirmation of the role and effectiveness of the remuneration model.

“It is important to note that this bonus can be paid due to the favourable financial outcome of 2007,” said Prof. Fourie.

“Our intention is to pass the maximum benefit possible on to staff without exceeding the limits of financial sustainability of the institution. For this reason, the negotiating parties reaffirmed their commitment to the Multiple-year Income-related Remuneration Improvement Model used as a framework for negotiations. The model and its applications are unique and has as a point of departure that the UFS must be and remain financially sustainable,” said Prof. Fourie and Prof. Johan Grobbelaar, Chairperson of UVPERSU and Spokesperson of the Joint Union Forum.

The agreement provides for the phasing in of fringe benefits of contract appointments for 2008. This includes the implementation of a pension/provident fund, housing allowance and the medical fund allowance as from 1 January 2008 to staff who are appointed on a contract basis.

Agreement was also reached that 1,0% will be allocated for structural adjustments in order to partially address the backlog in respect of remuneration packages of other higher education institutions. These adjustments will be made after further investigations during 2008.

The post levels that have been earmarked for adjustment are academic staff (associate professor, professor and dean) as well as certain post levels in the support services.

An additional R500 000 will be allocated to accelerate the rate of phasing in the medical fund allowances.

The implementation date for the salary adjustments is 1 January 2008, but could possibly be implemented only at a later stage due to logistical reasons. The adjustment will be calculated on the remuneration package.

The agreement also applies to all staff members of the Vista and Qwaqwa Campuses whose conditions of employment have already been aligned with those of the Main Campus.

Prof. Grobbelaar said that salary negotiations were never easy, but the model is an important tool. He said the Joint Union Forum illustrates that people from different groups can work together if they share the same commitment and goal.

In 2007, a total salary adjustment of 5,7% and a once-off non-pensionable bonus of R2 000 was paid to staff.
