ANALYSIS OF 440 MC RADIATION FROM THE SUN DURING THE ECLIPSE OF JULY 20, 1963.
Abstract
The sun at 440 mc on July 20, 1963 appeared as a disk of radius 1.1 times the optical radius of the sun. This value was somewhat lower than values obtained by observers on previous dates. However, July 20, 1963 was in a period of sunspot minimum, thus making the radius of 1.1 times optical size a realizable value. A radio plage on the eastern limb of the sun was detected from the radiation curve obtained during the first half of the eclipse. There were variations during the last half on the eclipse, but experi mental error in the equipment resulted in poor data for that period; therefore, no conclusions were made concerning the latter half of the eclipse. The temperature measurement of the sun at 440 mc indicated a temperature of about 800,000K, which was of the magnitude predicted. (Author)
