ScopeX 2011 Final Report
by Lerika Cross
ScopeX X has come and gone.
There were 23 amateur telescope exhibitors who showed off their 30 telescope exhibits and their equipment collectively had the largest light-
The ATM award winners judged by Chris Stewart and Dave Blane are in Chris’ ATM Report on the website.
Johann Swanepoel exhibited the two 20” telescopes he built. One he built for himself and this one he drove up from George in a Corsa bakkie. The other one he built for his friend Ron Edge who stays in Johannesburg and who kindly brought it along to ScopeX.
Also in the Corsa bakkie was Wim Filmalter (who hails from Riversdal and who met up with Johann at George) with his telescope exhibits. Johann and Wim remain good friends after spending ~ 30 hours together in the packed bakkie.
Not even Auke Slotegraaf -
So what was new this year?
The ScopeX Student Challenge – a new initiative introduced by ScopeX to encourage the youth to enter exhibits of astronomical relevance.
Many thanks for the support with this endeavour go to:
Jeremy Exelby, a Math teacher from Howick High, who provided enthusiasm to get the initiative off the ground, contributed the “Astronomy at your School” exhibit, exhibited his self-
Case Rijsdijk, who assisted with the brief for the Student Challenge and who also judged the exhibits;
Jane Webb, the teacher at the Oprah Winfrey Leadership Academy for Girls, who inspired 4 students to enter from her school.
The first winner of the Student Challenge was Montagu Thorne aged 13 (of Morningside Manor) with his homemade 6” Dobsonian telescope.
Brett Edwards, at the end of his AstroPhoto talk last year, said that he hopes 2011 brings a record number of AstroPhotos.
And so it was: a record 36 photos from 11 exhibitors.
The judges, Case Rijsdijk and Auke Slotegraaf declared the following winners:
"Centre of Milky Way Galaxy" by George Laikos
"Teapot region" by Pat Kuhn
"11 day old Moon" by Gerhard Koekemoer.
There was also a beautiful selection of photos that Johan Smit (ASSA Pretoria) displayed on behalf of his friend Doug Sharpe, a member of the Brough Astronomy Society in the UK (www.brough-
Many thanks, to all presenters of talks at ScopeX -
Jeremy Exelby, ASSA Midlands, presented ‘Moons of the Solar System” (Rob Pitroff);
Melaku Yigiletu, the National Laser Centre, presented "Light detection and Ranging (LIDAR) -
Roelf Botha -
Tim Cooper, ASSA Section Director – Comets and Meteors, presented “Chemistry of Comets”. Trevor writes “as usual Tim gave a wonderful talk, and much of what he said was new to even experienced visitors in the audience and therefore interesting. He led gently into what is a complex subject and spoke to the layman. He discussed the history of comet observations, leading up to obtaining dust samples from within the coma of one comet, to the analysis, usually spectroscopically, of the various hydrocarbon and silicate molecules present. He mentioned that the green colour of comet comas was caused by diatomic carbon, while I had understood up to that point that it was nickel. He ended his talk with a discussion of Comet 45P/Honda-
Case Rijsdijk – ASSA Director: Education & Public Communication presented "What's new in the Universe -
Auke Slotegraaf, Director ASSA Deep Sky Section, gave a talk about ‘Beyond the Jewel Box and 47 Tuc – next steps in exploring the deep sky’. Tim writes “Auke said that many of the observations he receives are of the same old well-
Kobus Olckers, Space Weather Officer: SANSA–Space Sciences, talked on “Space Weather: the impact of space weather on human activities” . Alec Jamieson who attended the talk writes: “Kobus informed us about the recent formation of the South African Space Agency and that the Magnetic Observatory at Hermanus is now part of this organization. Kobus explained how conditions on the Sun have an effect on the Earth and in space in the vicinity of the Earth. SANSA is part of an international effort to improve the understanding of phenomena like solar flares and coronal mass ejections (CME's), and the consequences of these on Earth. As some of these consequences can pose significant hazards, the Space Agency is striving to improve the accuracy of predictions about space weather, which is the term given to the overall effect on the Earth of the flow of charged particles from the Sun called the solar wind. Kobus explained how space weather creates the beautiful and harmless Northern Lights, and how it affects more practical things like long range radio propagation and electricity transmission. He touched on the potential of a severe space weather episode to cause failures in high voltage electrical equipment and therebya prolonged disruption of electricity transmission while repairs and replacements of equipment are made. Kobus ended off with the message that severe space weather effects are fortunately rare, and the ability to give warning of such events is improving. (Prof Matie Hoffman)
Ask an Astronomer: This session’s chair, Tim Cooper, writes “we were lucky to have not one, but two eminent astronomers at our disposal, with Professor Matie Hoffman travelling from Bloemfontein and Case Rijsdijk all the way from the Garden Route. Case mentioned that they have not had rain for some time as a result of which his Cape Ash trees are dying. He offered to take the Gauteng rain which has prevented us from observing for several months back with him, but it appears the airline refused him to take it onboard.Like a meteor shower (or waiting for a number 8 bus) there was a slow start to Ask an Astronomer, but then questions started to come in bunches. Mainly of a cosmology nature, people wanted to know more about black holes, white dwarfs, cosmic strings, and WIMPS. It turned out that the astronomers had an answer for just about everything, except the question about the existence of ‘white holes’. If you know what these are, answers on a postcard please.”
Baie dankie aan Hennie Maas vir die lewendige opname by ScopeX van die populêre program van Radio Sonder Grense, “Sterre en Planete”, met Prof Matie Hoffman van Univ van die Vrystaat en Kobus Olckers van SANSA. Baie dankie, Matie en Kobus. Die program is opgeneem en kan geluister word as ‘n RSG Potgooi.
