From about 1-3 EeV, results from the HiRes, Telescope Array, and Pierre Auger experiments all indicate that cosmic ray composition is light, probably protonic. Since this energy range is above the critical energy of the galactic magnetic field, if these cosmic rays are of galactic origin there should be an anisotropy in their arrival directions at the earth. We will present a calculation of how this anisotropy should appear, search the data of the Telescope Array surface detector for this effect, and if absent calculate an upper limit on the fraction of cosmic rays of energy 1-3 EeV that are of galactic origin.
