Abstract : Moon reflected signals were received for 360 hours or 39 days at 150.60 mc, and for 38 days at 413.25 mc. The n x 180 degrees ambiguity can probably be resolved on all of the days. A program has been written for using the California Computer Products plotter, which can be programmed to draw grid lines, label coordinates and write captions as well as plot curves. This plotter is to be used for the Faraday rotation angle and electron content plotting. The 150.6 mc receiver is being converted into a phase-locked receiver which will automatically stay tuned to the incoming signal. A biconical spiral antenna for receiving circular polarization at 150.6 mc has been built and tested. Some modifications are required before the antenna can be made operational. A thesis for the MS. degree, dealing with electron and ion temperature measurements for October 1964, is appended. (Author)
