Preliminary results on azimuthal asymmetries in leptoproduction of realphotons on an unpolarized hydrogen target measured at the HERMES experiment arepresented. The analysis of data taken with different beam charges andhelicities allows for a simultaneous extraction of asymmetries originating fromthe interference term and the squared DVCS amplitude. Sizeable asymmetryamplitudes for the first cosine moment of the beam-charge asymmetry and thefirst sine moment of the beam-spin asymmetry have been found. The results arecompared to different theoretical calculations.
