Description
The August 2014 NuSTAR observation of the Seyfert 2 galaxy NGC 1068 allowed us to discover a hard X-ray flux excess with respect to observations performed 20 months earlier and 6 months later. This variability was ascribed to an unveiling event during which Compton-thick material moved temporarily out of our line of sight enabling us to unveil the direct nuclear radiation of this buried AGN. In this talk, I will discuss the results of the latest NuSTAR monitoring campaign performed between July 2017 and February 2018 with the aim of searching for flux and spectral variability on shorter time-scales (from one up to six months) and providing some tighter constraints on the number of clouds of the circumnuclear absorbing Compton-thick material, their physical properties and their distance from the illuminating source.
