We have analyzed energetic proton, alpha particle, and electron measurments during two magnetopause crossings of ISEE 1 which show mgnetic field signatures characteristic of flux transfer events. While the ions are streaming highly collimated along the magnetic field, the electrons show either isotropic distributions or distributions which are consistent with convected small-scale structures. Fluxes and relative abundances of ions in flux transfer events are similar to the trapped particle values. We have observed similar particle signatures when no change in the magnetic field normal component has been measured. During the occurrence of isotropic electron distributions, the absolute electron flux (above 75 keV) is greatly reduced when compared with the flux of the trapped electron population. Thus the electrons cannot be explained by simple leakage out of the magnetosphere.
