IONOSPHERIC RESEARCH.

Abstract

Moon-reflected signals were received for 234 hours on 32 days at 150.6 MHz and for 61 hours on 31 days at 413.25 MHz. There were several important solar flares and two significant magnetic storms. The data have not been studied for correlation of electron content irregularities with these events. Uncertainties are present in 1966 data from August through December Integrated electron content to the F2 maximum from ionograms and the topside to bottomside ratio are being used to resolve these uncertainties. Topside to bottomside ratios for October 1965 are being calculated using both Ft. Monmouth and local ionograms. Seasonal averages for 1965 data from February 24 through November 3 are presented which are adjusted to a common solar flux at 2800 MHz for each season. These are little different from the unadjusted seasonal averages because the variation in solar activity for 1965 was low. An AFC unit for the 413.25 MHz receiver and a SCR elevation motor control are being constructed. Signals from the ATS-B stationary satellite over the Pacific have been received. (Author)
