  For a given solar magnetic field, the near-Sun (phase-space) density of
cosmic ray electrons and positrons of energy above about 10GeV can be
calculated from first principles, without any assumptions about the cosmic ray
diffusion. This is because the sunlight Compton drag must be more important
than diffusion. If the solar magnetic field has an appreciable dipole
component, the electron/positron density should have a belt-like dent, perhaps
extending to several solar radii. The belt structure appears because the
quasi-bound orbits are depopulated by the sunlight Compton drag.
