This note presents preliminary measurements of the Higgs boson properties measured in the H→γγn13 TeV by the ATLAS experiment at the LHC. Fiducial and differential cross section measurements are presented in a variety of phase space regions and as a function of several kinematic variables. The fiducial cross section is measured to be σfid=43.2b for a Higgs boson of mass 125.09 GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity |η|
