  A search for the Standard Model Higgs boson in the two photon decay channel
is reported, using 1.08 fb^-1 of proton-proton collision data at a
centre-of-mass energy of 7 TeV recorded by the ATLAS detector. No significant
excess is observed in the investigated mass range of 110-150 GeV. Upper limits
on the cross-section times branching ratio of between 2.0 and 5.8 times the
Standard Model prediction are derived for this mass range.
