Distribution of the Southern Auroral Zone

The historical development of our knowledge of the geographical distribution of auroras in the Antarctic is reviewed. The results for the IGY and later years as given by DAVIS, GARTLEIN, FELDSTEIN, and others are summarized. Data on azimuth of auroral arcs at various hours of the day are presented. The equatorward expansion and broadening of the auroral belt with world-wide features of magnetic storms are noted. Specific instances of auroral belt positions during very great and very weak magnetic disturbances are noted. This belt appears interlinked with the corresponding belt in the Arctic. The spatial relationships to geomagnetic and other geophysical phenomena are summarized

Morphology of Magnetic Storms

This publication is a product of the continuing study of the properties of charged particles and fields in space being conducted by The RAND Corporation under contract No. NAS5-276 for the National Aeronautics and Space Administration. Magnetic storms, revealed by world-wide changes in the intensity of the earth's magnetic field, and emphasized by disturbances in electromagnetic communication channels, form detectable patterns on the surface of the earth and above it. The author draws together data from various times, places, and altitudes and, coupling these with what is known or inferred about the aurora, the ionosphere, and the relationship between them and the earth's radiation belts, creates a picture of what is believed to occur during a magnetic storm
