Abstract : Moon reflected signals were received on 46 days during the quarter, for 382 hours at 150.6 mc. Signals at 413.25 mc were also received during 44 of the observation days, so that the total Faraday rotation angle could be resolved on those days. Diurnal average curves for observation periods in September, October, November and December, 1964, are presented. A master's thesis study dealing with the correlation of electron content irregularities and irregularities in the horizontal component of the earth's magnetic field is nearing completion. Using quantitative data from correlated irregularities, velocities of motion of ionospheric disturbances have been calculated which fit a 12-hour cycle. A thesis for the M.S. degree dealing with a comparison of methods of resolving the n x 180 degree ambiguity of the Faraday rotation angle is presented. Several new M.S. thesis studies have been started. (Author)
