Learners and teachers are invited to have their work flown in space in a new satellite project called ARISSat which replaces the originally SuitSat 2 project which was a disused spacesuit fitted with amateur radio equipment.

“The ARISSat-1 Team wishes to include a memory stick of files prepared by learners," explained Amateur Radio on the International Space Station (ARISS) International Chairman, Gaston Bertels, ON4WF. "This should be a .jpg or a PDF of things the student has prepared." He gave such examples as a paper or a study done on a STEM (science, technology, engineering, math) topic, a drawing of spacecraft or a schematic, a journal kept on a STEM topic, a story or news article about a STEM subject or a photo of the class doing a hands-on STEM activity. Having the students' work be a part of ARISSat-1 means the student is a part of the satellite project and along for the spacewalk and deployment of ARISSat-1."

"The quantity of files and the size of a file are unlimited, since memory sticks provide for a very large amount of file space." Bertels said that files must be either in .jpg or PDF format -- no Microsoft Word documents will be accepted. Files can be in any language, as long as an English translation is also included as a text file.

South African entries will be coordinated by SA AMSAT and also placed on a local website. Entries should reach by 28 February 2010.


The Hermanus Magnetic Observatory in collaboration with several other research institutions and universities in South Africa, will be responsible for the execution of several experiments related to Polar Space Weather studies. The experiments will be conducted on board the SA Agulhas, at the South African National Antarctic Programme’s (SANAP) base in Antarctica and on the South African Bases at Marion Island and Gough Island.

The HMO requires a suitably qualified (B.Eng, B.Tech or equivalent) Electronic Engineer with at least two years relevant experience or a M.Eng, MSc or M.Tech degree for a two and a half year contract appointment in the South African National Antarctic Expedition (SANAE 50) team to Antarctica for 2011. The minimum contract period will be from 1 May 2010 to 30 September 2012, but may commence sooner and extend later if necessary. The applicant will be trained at the HMO and may also be involved in short-term expeditions to Marion Island and Gough Island to set up instrumentation for the HMO during the training period at the HMO.

Applicants should complete the required HMO application form, submit a detailed CV together with the names and contact details of three referees, and covering letter summarizing the reasons for applying to The Antarctic Officer at to reach the HMO before 1 January 2010.

Hannes Coetzee, ZS6BZP, reports that the solar activity is still at low levels. An impressive sunspot cluster made its appearance on Wednesday. The solar flux level reached a new high of 83 for the current solar cycle. From another source it was learnt that about two days ago sunspot 1 035 was as wide as seven planets Earth. The fast-growing active region burst into view on 14 December with a magnetic polarity that clearly identifies it as a member of new Solar Cycle 24. If the expansion continues apace, it could soon become the largest sunspot of the year. Check for movies, photos and updates.

20 and 15 m will provide the best opportunities for DX. Conditions to India will be good from the afternoons onwards. During the late afternoons and early evenings it will be moderate towards Europa. In the afternoons there are good possibility of contacts with the USA on 15 m. Contacts with New-Zeeland will be possible for a short while on 15 m during the mornings. Contacts with Australia will be possible on 20 m during the afternoons. During the afternoons and evenings 20 and 15 m contacts may be possible with Brazil.

Local conditions are going to be good on 40 m during the day time. 80 m may perform well during the early mornings and late afternoons over the shorter distances. 30 m will perform well over the longer distances during the middle of the day. With summer here 20 m is also once again very useful for contacts over the longer distances, especially during the mornings. On Wednesday, when the new sunspot cluster made its appearance, propagation was experienced on frequencies as high as 15 m between Pretoria and Hermanus.

80 m is the frequency of choice in the evenings.

Please visit for further information.
