Variations in solar wind properties are dominated by a number of high speed streams. Some of them, due to bubbles of coronal matter ejected during solar flares, are transient, others, originating from coronal holes last for a significant fraction of a solar rotation. By interacting with the quiet wind, these fast streams give rise in the first case to a travelling shock wave, in the second case to a pair of forward and backward shock waves, by which the interaction region, corotating with the sun, is bounded. In both cases, high fluxes of energetic ions (- MeV) are observed in the vicinity of the shock : these are « the energetic storm particles » and « the corotating particle events » respectively. Two acceleration mechanisms are invoked t...
