DESCRIPTION:We discuss the calculation of the NNLO corrections to the phot
 on energy spectrum in the rare B -> X_s gamma decay in the Standard Model.
  The leading corrections to the spectrum\, coming from the interference of
  graphs including the magnetic dipole operator O_7\, were calculated indep
 endently by two groups and they were recently included in the first estima
 te of the B -> X_s gamma branching ratio at NNLO. The calculation of corre
 ctions to the spectrum coming from other operators is currently under way.
