To refresh the memory of MAB (and anyone else who doesn't remember the
earlier discussion), the South Atlantic Anomaly is an area where the
Van Allen belts are unusually close to Earth's surface.  This is of
concern to spaceflight planners because an orbit which passes through
the S.A.A. will result in higher radiation doses than one which does
not.  For long missions, this influences considerations like the need
for shielded storage for photographic film.
