Analysis and measurement of terrestrial magnetism study of rapid fluctuations of the geomagnetic field. Research was directed toward the study of rapid fluctuations of the geomagnetic field. An investigation was made of the characteristics and origins of the natural magnetic field fluctuations in the frequency range of approximately 0.01 to 50 cps with particular emphasis on frequencies from about 0.1 to 3 cps. Field records were made of the fluctuations. Early records obtained for analysis and a study into the relationship of the results to magnetic disturbances and other geological phenomena were provided to Air Force Research Cambridge, Terrestrial Science Group. The work described in this report covers the hardware phase of the installation of the measurement facilities at Strawberry Hill Field site Concord, Massachusetts. A description of the instrumentation and early measurements taken are given. Full time data gathering of the 0.01 to 3 cps geomagnetic fluctuations is in progress at the conclusion of this contract.
