✦ Synopsis

The new TeePee Tee array of the Clark Lake Radio Observatory has been used to observe the quiet Sun at 121.5, 73.8 and 26.3Mtlz. The equatorial brightness distributions at all three frequencies, and the polar brightness distributions at the two higher ones have been measured. From the observed total fluxes and half-power diameters we have derived the peak brighmess temperatures of the solar disk as well as of some sources of the slowly xarying component. * On leave of absence from Instituto Argentino de II.adioastrononlia, Argentina.
