To characterize the performance of MAGIC under moonlight we used 174 hours of Crab Nebula observations taken between October 2013 and January 2016, under NSB conditions going from 1 (dark) up to 30 x NSBDark4.When dividing the data we aimed to have rather narrow NSB bins while keeping sufficient statistics in each of them (~ 10 hours per bin).Observations were carried out in the so-called wobble mode (Fomin et al., 1994), with a standard wobble offset of 0.4o.
