 Abstract
 The beamhelicity asymmetry in associated electroproduction of real photons, ep > aEuro parts per thousand e gamma pi N , in the Delta(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 > aEuro parts per thousand e gamma pi(0) p and ep > aEuro parts per thousand e gamma pi(+) n, from a data set collected with a recoil detector. All asymmetry amplitudes are found to be consistent with zero.
