The Galah Survey update

The GALAH (GALactic Archaeology with HERMES) survey is a large observing program that is using the HERMES spectrograph at the Anglo-Australian Telescope to measure the chemical compositions and radial velocities of 1 million stars in the Milky Way. Our main science goal is to identify chemically similar groups of stars in the Galactic disk, which are most likely long- disrupted star clusters, to decipher the star formation, chemical enrichment, stellar migration and merger history of the Milky Way. In this talk I will give an overview of the HERMES instrument, the survey and present its current status.
