GRAAL is the adaptive optics module feeding the wide-field IR imager HAWK-I at the VLT observatory. As part of the adaptive optics facility, GRAAL is equipped with 4 Laser-guide star wave-front sensors and provides a large field-of-view, ground layer correction system to HAWK-I. GRAAL is installed in Chile and undergoing commissioning. We report on the latest results with the module and the outlook before the operation start in 2018.
