This Friday 29th July at 8pm for our members night we have our own Jacquie Milner speaking to us about “A visit to four impact structures in WA“:

The ancient and heavily eroded landscape of Western Australia offers an opportunity to see some of the major features of meteorite impact sites.  In September 2004 a small group of members from the Perth Observatory Volunteer Group and the Geological Society of WA toured around four impact structures in central Western Australia:  The Yarrabubba Impact Structure, revealing the deep effects of a strike;  the renamed Shoemaker Impact Structure (formerly known as the Teague Ring) displaying some of the surface features of a complex crater; the well-known Dalgaranga Crater, a good example of the simple crater; and the Yallallie Impact Structure, formed in an unusual setting.  Together these structures provide an overview of impact structure geology, both above and below ground.


If you have a telescope and would like to know how to use it, or alternatively, would like to show it off to us, please bring it along!

Members’ Night is on every Friday night commencing at 8PM (doors open 7:30PM). Guests of members are always welcome.
