Welcome to the Astronomical Society of South Australia

The Astronomical Society of South Australia is the only representative body for amateur astronomy in the state of South Australia. Founded in 1892 and with around 600 members, it is the oldest and one of the largest organisations of its kind in Australia.

Our monthly meetings, which usually feature a guest speaker, are free, open to the public and visitors are most welcome to attend.

Jovian Planets Astronomy Education

Wednesday, 1 March 2017 7:00 PM

Out past the main asteroid belt lies the realm of the giant planets. This month we find out how the four gas planets formed and become so large. We will also look at their internal structure and explore the different ring systems circling each of these worlds.

How We Dodged a Doomsday Event in 2012 General Meeting

Wednesday, 1 March 2017 8:00 PM

In September 1859 the most powerful solar storm in recorded history wreaked havoc on our, then, fledgling technology. Known as the Carrington Event, it is inevitable that a storm of similar ferocity will happen again, but the consequences for our more advanced and more vulnerable technologies could be far worse. In July 2012 a Carrington-type event, that went largely unreported in the media, fortunately missed the Earth, but slammed into an orbiting solar observatory. In his talk Dr Russell Cockman will review the circumstances of the Carrington event, the potential cost of a similar event to our present way of life, what was learned from the observations collected in July 2012 and how the damaging impacts can be mitigated.
