STUDY OF GEOMAGNETIC FLUCTUATIONS
Abstract
A continuing study of fluctuations of the earth's magnetic field is described. Its purpose has been to record and analyze fluctuations within the frequency range 1 to 50 cycles per second. Analysis is directed toward relating these fluctuations to specific causes. Three orthogonal components are recorded. Data has been obtained for various periods up to a year or more from individual recording stations at College, Alaska; Ft. Devens, Massachusetts; Thule, Greenland; Mt. Evans, Colorado; Huancayo, Peru; and Shickley, Nebraska. Reduction of data to digital form is accomplished by a semi-automatic data- processing system. Output of the system is a series of numbers representing ean hourly activity within six one-octave bands for each component. These bands are centered at 1.5, 2.75, 5.0, 10.0, 20.0 and 40.0 cycles per second. Part of the available data has been reduced and a start made on its analysis. There appears to be a positive c rrelati n between meteor activity and geomagnetic fluctuations in the 1 to 2 cycle per second range, which is to be studied further.
