Resumo
A strong S-component of solar radiation was identified during the total solar eclipse of November 12, 1966. Its characteristics, as measured at 4.28 cm, were studied in terms of flux and polarization, and its spectral features were derived by the use of data from other observatories. The whole source presented approximately the typical characteristics suggested by some authors in the last few years, and further it has been shown that it could be resolved into at least two enhanced regions, one showing unpolarized radiation with a brightness temperature Tb≈ 1.2 × 106 °K, and the other showing 50% of left-handed circularly polarized radiation, with Tb≈ 0.7 × 106 °K. The source's overall characteristics favour the presence of non-thermal absorption at the emitting regions. © 1968 D. Reidel Publishing Company.
