High time resolution solar wind ion flux and interplanetary magnetic field measurements made by INTERBALL-1 satellite are used for the investigation of solar wind modifications in the foreshock region. High positive correlation (correlation coefficient is about 0.8) between ion flux and magnetic field fast variations with large amplitude inside the foreshock are found. Simultaneous observations by INTERBALL-1, GEOTAIL, IMP 8 and WIND near Earth’s bow shock allow us to estimate the motion of outer foreshock boundary. VOYAGER-1 data obtained during flyby near Jupiter are studied to compare Jupiter’s foreshock characteristics with near Earth’s ones.
