17640 Mount Stromlo           Discovered 1996 Aug. 15 by R. H. McNaught and J. B. Child at Macquarie.
Home to Australia's oldest telescopes and latest technologies, Mt. Stromlo Observatory was devastated by fire on 2003 Jan. 18. Since the installation of the Oddie refractor in 1910, the staff contributed greatly to the astronomical community, including support for the Canberra Astronomical Society and amateur astronomy.
