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.

Ensure your place at the UFS

2010-10-27

The University of the Free State (UFS) appeals to all prospective South African students who want to come and study at the UFS in 2011 to submit their applications no later than Tuesday, 30 November 2010.

The UFS is aware of the fact that learners will not have received their final Grade 12 results by Tuesday, 30 November 2010; therefore provisional admission will be granted based on learners’ most recent Grade 12 results. Final admission will take place upon receipt of the final Grade 12 results, which will be available early in January 2011.

Prospective students can obtain application forms for admission at the following places:

The UFS’s web site at www.ufs.ac.za,
The Information Office (Unit for Prospective Students) at the Thakaneng Bridge on the UFS’s Main Campus in Bloemfontein,
You may also send an e-mail to info@ufs.ac.za or
Phone 051 401 3000 and the necessary forms will be posted to you.

Senior undergraduate students (that is all students who were registered up to and during 2010 at the UFS) as well as post-graduate students, must self-register electronically on-line from Monday, 1 November 2010 until Tuesday, 4 January 2011. This includes master’s and doctoral students.

In order to encourage senior students to register online, the UFS offers 20 laptops as incentives for the senior students who successfully register online from 1 November 2010. These laptops will be handed over to the winners after the registration process in 2011.

Registration of first-year students:

The Rector and Vice-Chancellor, Prof. Jonathan Jansen, will welcome first-year students on Friday, 14 January and Saturday, 15 January 2011, respectively, in the Callie Human Centre. The Faculties of Economic and Management Sciences, the Humanities and Education will be welcomed on 14 January 2011 and the students of the Faculties of Natural and Agricultural Sciences, Law and Theology shall be welcomed on 15 January 2011. The compulsory orientation programme for new first-years will also then commence.

From 17 to 21 January 2011 first-year students will receive academic advice at the Callie Human Centre, whereafter they will be referred for self-registration. These processes will take place according to the set timetable. This timetable is available in the Kovsie Guide that will be sent to learners as soon as we have received their applications, as well as on the web site of the UFS at www.ufs.ac.za/register2011.

First-year students’ fees must be paid prior to arrival on 14 and 15 January 2011.

Registration of senior students:

Senior students who experience problems with the electronic on-line self-registration process have the opportunity to resolve problems within a programme on campus from Wednesday, 5 January until Wednesday, 12 January 2011. This programme will be sent out to students and is also available at www.ufs.ac.za/register2011. The specific scheduled day for senior students to resolve problems is the last and only day to resolve the problem.

Senior students can also contact 051 401 9111 for more information in this regard.

Students may register for prescribed modules for 2011, even though the November 2010 examination results are not yet available. Changes resulting from examination results that are made available later can be done up to and including 28 January 2011.

In terms of applications for senior students, only students who have interrupted a calendar year of study need to re-apply for admission.

Registration of students at the UFS’s Qwaqwa Campus:

Senior and first-year students of the UFS’s Qwaqwa Campus register from Wednesday, 12 January until Friday, 28 January 2011 in the Nelson Mandela Hall on this campus.

Registration of students at the UFS South Campus:

First-year students from the UFS’s South Campus in the University Preparation Programme and the Extended Programme (only Natural and Agricultural Sciences) register from Monday, 24 January till Friday, 28 January 2011 in the Arena Hall on the South Campus.

Students who have successfully completed the University Preparation Programme register with the first-year students on the UFS Main Campus on Friday, 14 and Saturday, 15 January 2011 – according to faculties (cf. paragraph 6).

Lectures for all students shall commence on Monday, 24 January 2011.
