Abstract : Techniques used and results obtained in the observation of the solar eclipse of 15 Feb 1961 at a wavelength of 4.3 millimeters are described. Measurements during the period in which the sun was being eclipsed showed a variation in emission as great as two to one between regions that were larger than 0.1 of the solar disc. During the period of solar occultation a mean radiating temperature of 200 K was observed, which was equal to the emission temperature of the moon. Approximately 30 seconds after the second contact, a brightness temperature of approximately 200 K was observed at the western edge of the moon. This was attributed to a solar flare. (Author)
