Abstract content
Cosmic ray fluctuations with the periods less than 3 h by data of the EPAM/LEMS120 aboard ACE spacecraft are studied. It is shown that the frequency spectra of cosmic rays undergo significant dynamic changes caused by the presence of fast magnetosonic waves in the solar wind. Evidences of generation of fast magnetosonic waves by the SEP fluxes have been found.
