Wed10Feb20217:30 pmQueens Domain ClubroomsListening to the Planets PresentationWe are very lucky to have Dr. Mike Groth VK7MJ giving us a presentation on Listening to the Planets.Decametric Radio emissions from the planet Jupiter, were first identified by Burke and Franklin while calibrating a 22 MHz antenna array in Maryland USA in 1955.This was later confirmed by data collected by Alex Shain in Australia some 4 years earlier, and opened a new field of planetary astronomy.This talk is a brief outline of the early history of decametric radio astronomy and how observations in Tasmania and New Zealand between 1971 and 1975, provided the first dynamic spectra of the Jovian radio bursts.In the true ANZAC tradition, all this was achieved on a shoestring budget, and using an early generation of domestic videotape recorders in a way their manufactures never intended.This should be a fascinating talk as this was the subject of Mike's PhD!We will also stream the presentation on the REAST YouTube channel and on DVB-T around Hobart.https://www.reast.asn.au/news-events/live-stream/

A huge thank you to REAST Member Andrew Elwell for giving us a talk on the Pawsey Supercomputing Centre.
This centre is based in Western Australia and Andrew is a Supercomputing Systems Administrator who works remotely from his home in Cygnet, Tasmania.
The Pawsey Supercomputing Centre prides itself on incorporating a range of best practices, features and solutions. Key features of the Centre include:
- A purpose-built supercomputing building of more than 1000 m2 at Technology Park in Kensington, Western Australia; complete with scalable cooling and electrical services, to accommodate for expanding supercomputing infrastructure within the facility
- A unique groundwater cooling system for removing heat from the supercomputer and dissipating this heat via an aquifer, 140 metres below the Centre, with no loss of groundwater.
- A photovoltaic system which has been incorporated into the building’s shaded façade, plus an extensive PV array on the roof of the building
- This installation generates 140 kW of electricity onsite, which acts to offset the electrical and CO2 footprint of the Supercomputing Centre
- Automated ‘intelligence’ incorporated into the building, with real-time monitoring, to facilitate efficient operation and support fine tuning of operations to reduce overall power costs
Andrew will be covering the centre, its history, who was Joe Pawsey and the work being undertaken to process the data from the Square Kilometre Array radio astronomy project.
This should be a fascinating presentation.
One not to be missed.

Our REAST May presentation night will be a talk by Dr. Mike Groth VK7MJ on many lightning derived phenomena.
While Army Signalers in the trenches in France during the First World War were using early valve amplifiers to detect the earth currents generated by the field telephones in the enemy trenches, they discovered that the earth generated a range of strange audio frequency signals, including clicks, tweaks, and whistling.
These remained a scientific curiosity for almost 40 years, until the International Geophysical Year in 1957-8, when they became a tool for exploring the electrical and magnetic properties of the Earth’s magnetosphere before the development of specialised geophysical monitoring satellites in the 1970’s.
This will include many fascinating phenomena that Mike come across whilst undertaking his research in New Zealand featured in his Listening to the Planets presentation.
This should be another REAST Presentation not to be missed.
Thanks to Mike for offering to give the presentation.
