     We propose to carry out a study of five gamma-ray burst error boxes
    in the hither to unexplored ASCA energy range.  Three of them contain
    weak ROSAT or Einstein sources, and have been studied in the optical
    and radio ranges; we are anxious to determine whether their spectra
    contain high energy, non-thermal components.  The other error boxes
    have not yet been studied in the X-ray range.  Observations extending
    to 12 keV are particularly important in view of predictions that
    accreting, magnetized compact objects may emit a significant fraction
    of their luminosities as non-thermal radiation just below the
    cyclotron frequency.  The ASCA observations willbe complemented with
    deep radio, IR, optical and EUV observations.
