Abstract
The shielding that the Earth's magnetic field provides from solar emissions and cosmic rays is significantly less in the south Atlantic
and satellites that pass over the area suffer higher radiation damage. During the observation period the SAA has been deepening
and growing in extent. This, combined with the decline since 1985 of solar parameters that control the shielding the heliospheric
magnetic field provides from galactic cosmic rays, means that damage to satellites is expected to increase in the future.
