A Study of Currents in the Middle and Outer Magnetosphere

The purpose of this grant was to study the electrical current flow along and across the magnetic field lines in the middle and outer magnetosphere. These currents are both time stationary and fluctuating. Our study of the time stationary currents formed part of the Masters dissertation of graduate student Tom Meseroll. In the bibliography below we list the papers in journals and at meetings arising from these studies. In addition to these studies, we were asked to assist in several studies of the currents in the magnetotail, in the dayside magnetosphere, and near the polar cusp (with Hawkeye data). Also we undertook a study of the currents associated with sudden impulses caused by sudden solar wind pressure changes. Below we say a few words about these studies. This is followed by a bibliography listing the papers. There were no patents issued or inventions associated with this study.
