A Monte Carlo simulation of the propagation of relativistic solar flare protons in the interplanetary magnetic field was used to understand the intensity-time profiles and anisotropies for the GLEs on November 22, 1977 and May 7, 1978. Mean free path for pitch angle scattering of 0.5 AU and 5 AU, respectively, were deduced. The injection of the solar flare protons had an extended time structure that was found to be of similar shape as the x ray burst profiles in the bands 1-8 A and 0.5-4 A, respectively.
