Abstract : This anaysis describes the 4.3 mm wavelength measurement of lunar emissions during a lunation and during the 25 Aug 161 eclipse, the results of the measurements and the relationship of the results to measurement at other wavelengths. The maximum and minimum temperatures observed with a 0.2 degree beamwidth antenna during a lunation was 260 and 145 K respectively. The temperature change associated with the lunar occultation during the eclipse was approximately 10 C. The temperature change during the eclipse is hypothesized as being associated with the change in temperature of the dust layer. (Author)
