• A bstract The beam-helicity asymmetry in associated electroproduction of real photons, ep  →  e γπ N , in the Δ(1232)-resonance region is measured using the longitudinally polarized Hera positron beam and an unpolarized hydrogen target. Azimuthal Fourier amplitudes of this asymmetry are extracted separately for two channels, ep  →  e γπ 0 p and ep  →  e γπ + n , from a data set collected with a recoil detector. All asymmetry amplitudes are found to be consistent with zero.
