The behavior of ULF activity in the Pc5-6/Pi3 band (1-7mHz) on a global scale during the main phase of the intense magnetic storm on May 15, 1997, is studied using data from stations in the INTERMAGNET, Greenland Coast Array, IMAGE, and CPMN (210 MM) networks. Two regions of long-period broad-band ULF intensification are observed during the magnetic storm: one is in the early morning hours, the other is near dusk. The first one is, probably, related to an energetic electron injection, whereas the other one is due to the injection of ring current protons. It is suggested that ULF waves may be an intermediate agent transferring energy from the ring current protons/electrons to the relativistic electrons. The azimuthal scale of ULF disturbances in the dusk sector as determined from the IMAGE array was about 500km, which is an order of magnitude less than had been often assumed in modeling of resonant electron acceleration by MHD waves. The features of the observed broad-band ULF oscillations impose some constraints on models of relativistic electron acceleration by MHD waves during magnetic storms.
