Abstract : The primary activity of the U. of C.'s Space Science Group is the study of magnetic field measurements made by fluxgate magnetometers on spacecraft in the magnetosphere, in the solar wind and in space around other planets. Topics include: the solar wind and its internal structure; the solar wind interaction with planetary bodies; structure and dynamics of planetary magnetic fields; quantitative models of planetary fields and current systems; origins of magnetic activity; sources and properties of Ultra Low Frequency Waves; and effects of tectonic stress on rock magnetism. The faculty and research staff Group have collectively published more than 400 papers during 15 years of active involvement in the space program. ONR sponsored research has covered several subtopics within the general area of solar-terrestrial physics. These include: solar wind controlled dayside magnetic pulsations; substorm associated magnetic pulsations; magnetic storms, and magnetospheric substorms. The primary goal of this research is to understand the sequence of physical processes through which energy is transferred from the solar wind to the magnetosphere, and ultimately to the earth's atmosphere. One approach is the study of magnetic perturbations, within the magnetosphere and on the ground, caused by changes in the solar wind.
