The GALAH survey is excited to announce our second data release on 18 April 2018. It contains data for 342682 stars with up to 23 elemental abundances per star.

Update: On 9 May 2018 we released the GALAH survey DR2.1. This contains a fix to three columns related to radial velocities, populates the gaia_dr2_id column, and adds a collection of high-SNR median spectra. See the changelog for more details.

The catalogue is accessible through:
