    The authors report on a set of eight solar hard X-ray bursts corresponding to M-class flares and well-observed with the RHESSI and HXRS instruments. They find that the impulsive phases of these events invariably show the soft-hard-soft spectral pattern in which the power-law spectral index anticorrelates with the flux.
