"MATISSE made its first fringes on the star Sirius during the night between 18 and 19 February, with 4 telescopes, simultaneously in the L- and N-bands (atmospheric windows at 3 microns and 10 microns).
This major milestone of the project marks the end of the instrument integration, and the start of the commissionning period, that will last from now up to early 2019. The commissioning will fully qualify the instrument's performances, before its grand opening by ESO to the whole scientific community.
