The brightness distribution near the solar limb has been investigated by means of a technique in which derivatives of drift scans of the Sun were compared with derivatives of drift scans of the Moon. The results obtained at 88.3 GHz (3.4 ram) indicate that the Sun is limb neutral within the uncertai

โฆ Synopsis
The authors have previously discussed an improved method for obtaining the absolute solar brightness temperature using the new Moon as a calibration source. New measurements of the Sun-to-new Moon ratio at three frequencies near 36 GHz ()t = 8 mm) and also at two frequencies near 93 GHz ()t = 3 mm) are reported. The slopes of the solar brightness temperature spectrum based on these ratios are then discussed. The absolute solar brightness spectrum derived from all current available measurements is also presented and discussed.

The radio brightness distribution at 29 mm, 23.5 mm and 21.2 mm is calculated employing a statistical technique to account for the presence of spicules randomly occurring along the ray path. The results indicate limb brightening at each wavelength when the Avery and House (1969) spicule model is emp
Some properties of solar active regions at 9, 3.5 and 1.2 mm wavelengths are discussed. The regions have excess brightness temperatures of up to 1000, 700 and 150 K at 9, 3.5 and 1.2 mm wavelengths. The background radiation at 3.5 mm is often seen to be 'absorbed' in regions closely coincident with
A study of the circular polarization structure of solar active regions has been made from data obtained at 3.5 mm wavelength, using the 36 ft diameter radio telescope of the National Radio Astronomy Observatory at Kitt Peak, Arizona. The angular resolution of the telescope at this wavelength is 1:2.
