A formal observatory has flourished on the site since 1924, overcoming light pollution by establishing a major outstation with international cooperation and overcoming bushfire devastation to rebuild on its strengths. Over time the Mount Stromlo Observatory has evolved from solar observation through optical munitions manufacture to be the centre of optical stellar research in Australia and a world figure in astrophysics and associated instrumentation. By developing its capability in instrumentation coupled with world class testing facilities, it has become a major partner in the developing Australian space industry, and a designer and supplier of components for the world’s largest optical telescopes while continuing as a leading research institution. -
Skymapper Stellar Parameters for Galactic Archaeology on a Grand-Scale

D. Mackey1;2, T. Nordlander1;2, D. Yong1;2 and M. Bessell1 1 Research School of Astronomy and Astrophysics, Mount Stromlo Observatory, The Australian National University, ACT 2611, Australia 2 ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) Received; accepted ABSTRACT The SkyMapper photometric surveys provides uvgriz photometry for several millions sources in the Southern sky. We use DR1.1 to explore the quality of its photometry, and develop a formalism to homogenise zero-points across the sky using stellar effective temperatures. Physical flux transformations, and zero-points appropriate for this release are derived, along with relations linking colour indices to stellar parameters. Reddening-free pseudo-colours and pseudo-magnitudes are also introduced. For late-type stars which are best suited for Galactic Archaeology, we show that SkyMapper+2MASS are able to deliver a precision better than 100 K in effective temperatures (depending on the filters), ∼ 0:2 dex for metallicities above −2, and a reliable distinction between M-dwarfs and -giants. Together with astrometric and as- teroseismic space mission, SkyMapper promises to be a treasure trove for stellar and Galactic studies. Key words: stars: fundamental parameters – stars: late-type – Galaxy: stellar content 1 INTRODUCTION shifted ∼ 200 Å towards the blue to be even more sensitive at low metallicities, similarly to the DDO38 filter (McClure 1976). The Photometric systems and filters are designed to be sensitive to cer- only other existing all-sky survey measuring intermediate uv pho- tain spectral features. -

We describe our robotic facility for rapid transient follow-up, which can target most of the sky at δ < +10 deg to a depth of iAB ≈ 20 mag. We have implemented a new software pipeline to receive LIGO/Virgo alerts, schedule observations and examine the incoming real-time data stream for transient candidates. We adopt a real-bogus classifier using ensemble-based machine learning techniques, attaining high completeness (∼98%) and purity (∼91%) over our whole magnitude range. -

The SkyMapper filter-set contains a metallicity-sensitive intermediate-band v filter covering the prominent Ca II K feature at 3933.7 A.˚ When combined with photometry from the SkyMapper u; g, and i filters, we demonstrate that v band photometry can be used to obtain stellar metallicities with a precision of 0:20 dex when [Fe/H] > 2:5, and 0:34 dex when [Fe/H] < 2:5. Since the u and v filters bracket the∼ Balmer Jump at 3646 A,˚− we also find∼ that the filter-set can be− used to derive surface gravities. We thus derive photometric metallicities and surface gravities for all stars down to a magnitude of g 20 within 75 arcminutes of Tucana II. Photometric metallicity and surface gravity cuts remove nearly∼ all foreground∼ contamination. By incorporating Gaia proper motions, we derive quantitative membership probabilities which recover all known members on the red giant branch of Tucana II. -
