This year marks the 100^th anniversary of the establishment of the Commonwealth Solar Observatory at Mount Stromlo, now the site of Mount Stromlo Observatory and the ANU Research School of Astronomy and Astrophysics (RSAA). Mount Stromlo has an incredible legacy of discovery and has been central to many aspects of Australian astronomical research. To celebrate this milestone, the Research School of Astronomy and Astrophysics will be hosting a 1-day symposium at the Shine Dome in Canberra on 18 September which will highlight the contributions of scientists at Mount Stromlo followed by a gala dinner.

Confirmed speakers for the symposium include:

• Matthew Bailes
• Warrick Couch
• Tamara Davis
• Ron Ekers
• Ken Freeman
• Lisa Kewley
• Chiaki Kobayashi
• Anna Moore
• Elaine Sadler
• Brian Schmidt
• Rob Sharp

All members of the Australian astronomy community, and especially Mount Stromlo alumni, are invited to join us for this special event.

This year the Research School of Astronomy and Astrophysics students have decided to hold their annual Mount Stromlo Student Seminars adjacent to the symposium, on 19 and 20 September, providing an opportunity for PhD students from all institutions to also attend the symposium.

Registration will be free for both the 100^th anniversary symposium and the Stromlo Student Seminars.
