IONOSPHERIC RESEARCH
Abstract
Moon reflected signals were received at 150.6 MHz and 413.25 MHz on 35 days for 330 and 64 hours of operation, respectively. The operational times are summarized in tabular and in graphical form. Solid state servo amplifiers using SCR's are in operation for both azimuthal and elevation control. Circuit diagrams and brief descriptions of operation are given. Uncertainties in some of the 413.25 MHz data for 1966 are being resolved using ionograms. Some topside to bottomside ratios for 1965 data have been calculated. Signals from ATS-1 were recorded from 1120 CST May 21 to 0210 CST May 28. This period included several major solar flares and a severe magnetic storm May 25-27. The electron content data for May 21 and May 23 are presented. At the time of the flare on May 21 there was an increase of 1.6 x 10 to the 16th power electrons per square meter in 5 minutes. On May 23, at the time of the flare there was an increase of 3.2 x 10 to the 16th power electrons per square meter in 15 minutes. Data showing unusual effects during the magnetic storm May 25 are withheld, pending further study.
