Analytical expressions for the density and energization of field-aligned protons backstreaming from the Earth's bow shock are compared with data from the ISEE-2 solar wind experiment. Good agreement is found. It is shown how the analytical formulas can be derived from a simple model of the gross features of the reflection process. The model assumes a deceleration of the incident solar wind bulk velocity to take place in the foot region of the shock, followed by a magnetic mirroring in the deHoffmann-Teller shock frame of reference. Conservation of the magnetic moment of the particles is implicitly assumed. Despite the uncertainties associated with this, and other assumptions in the model, comparisons with observations show good agreement.
