Abstract : Moon reflected signals were received at 150.6 mc on 30 days for 204 hours of operation and at 413.25 mc on 29 days for 56 hours of operation. Most of the days were magnetically quiet. There were importance 2 flares on some of the days. The receiving station may be operated automatically on 150.6 mc. A thesis for the M.S. degree which gives details of the automatic operation is appended. The ratio of the topside to bottomside ionospheric electron content is being calculated for October 1965 using Ft. Monmouth ionograms and lunar reflection data. Volume IV of the Atlas of Lunar Data, for observation days from January 1 through December 31, 1965 has been distributed. Signals from the stationary satellite ATS-1 have been successfully received and recorded on two frequencies near 136 mc. (Author)
