For more than 30 years comma it has been assumed that a pc-scale torus produces a constant Compton-reflection component in heavily obscured AGN. We recently finished the 157-month Swift BAT processing and found to our surprise that nearly all of the brightest CT AGN are variable. We propose a variability study of 10 CT AGN with significant variability detected in multi-epoch NuSTAR observations at 2-10 keV comma where a significant reflection component was detected comma but none or only one high S-N soft X-ray observation exists so the observations are poorly constrained. This is a time critical opportunity to take advantage of a recent large set of legacy NuSTAR observations from this summer to study shorter virgul1 year-long variability periods in CT AGN.
