Variations of geomagnetic cutoff rigidity in the southern hemisphere close to 70 degrees W (South-Atlantic Anomaly and Antarctic zones) in the period 1975-2010

We report the existence of rapid variations in (effective) geomagnetic cutoff rigidity (Rc) between the equatorial and Antarctic zones adjacent to the Andes Mountains, revealed by the variation rate of geomagnetic cutoff rigidity (VRc) in the period 1975- The authors are grateful for the help and de...

Description
Summary:We report the existence of rapid variations in (effective) geomagnetic cutoff rigidity (Rc) between the equatorial and Antarctic zones adjacent to the Andes Mountains, revealed by the variation rate of geomagnetic cutoff rigidity (VRc) in the period 1975- The authors are grateful for the help and dedication that was given by the Editor and anonymous referee. The authors also thank Dr. E. Zesta (UCLA-IGPP), and Dr. L.A. Raggi (Incas-U.Chile) for their collaboration and support.
