Abstract : During the period of performance a program of instrument construction, technique development, data acquisition, and data analysis was carried out in order to characterize the auroral electrojet and the ambient and modified D-region directly above and near the HAARP (High Frequency Active Auroral Research Program) facility in Alaska. To accomplish this goal, five VLF D-region diagnostic systems were constructed and deployed in five High Schools near the HAARP facility and along the west coast of Alaska. In addition in order to characterize the auroral electrojet on a continental scale and to allow prediction of its location, four VLF D-region diagnostic systems were constructed and deployed in four High Schools on the east coast of the United States and Canada. Data from the complete array of D-region diagnostic systems was acquired during a number of Fall and Spring HAARP campaigns during the period of performance. This data was then used to determine the state of the D-region above HAARP during the campaigns and to provide information on the location of the auroral electrojet. The salient scientific results from the observations were published in the scientific literature and also reported at the annual RF Ionospheric Interactions Workshop in Santa Fe, New Mexico. In addition a portion of this data formed one of the bases of a Ph.D. dissertation completed at Stanford University.
