We have investigated two energetic particle events (28 keV ‐ 145 keV) upstream of the earth’s bow shock with two identical experiments of the Max‐Planck‐Institut/University of Maryland on ISEE‐1 and ISEE‐3. Close to the bow shock the particle distribution is more or less isotropic and indicates strong scattering of these particles in the upstream wave field. At ISEE‐3 the particles move essentially scatter‐free from the general bow shock direction. The temporal evolution of the particle bursts is discussed in terms of the interplanetary magnetic field topology and the scattering conditions.
