Abstract : Absolute flux density, height, and directivity of a strong source of the slowly varying component of solar millimeter emissions are discussed. The mechanism of gyromagnetic emissions is suggested to explain the observed flux spectrum, as well as peculiar emissions from unipolar spots at the solar limb. It is believed that the highly active sources of millimeter emissions tend to lie at a relatively higher level in the solar atmosphere than does the average of lower activity sources. A routine observation of solar sources of millimeter wavelength emissions is being conducted with a more refined mapping technique. (Author)
