  In eight years of operation, the Fermi Large Area Telescope (LAT) has
detected a large sample of cosmic-ray protons. The LAT's wide field of view and
full-sky coverage make it an excellent instrument for studying anisotropy in
the arrival directions of protons at all angular scales. These capabilities
enable the LAT to make a full-sky 2D measurement of cosmic-ray proton
anisotropy complementary to many recent TeV measurements, which are only
sensitive to the right ascension component of the anisotropy. Any detected
anisotropy probes the structure of the local interstellar magnetic field or
could indicate the presence of a nearby source. We present the first results
from the Fermi-LAT Collaboration on the full-sky angular power spectrum of
protons from approximately 100 GeV - 10 TeV.
