✦ Synopsis


The circular polarization from coronal condensations at ). =4.3 cm correspond to the extraordinary mode of propagation, due to the contribution of preceding spots' polarities, being usually left-handed. The fewer cases of right-handed polarization are normally associated to an excess of sunspot plages in the southern hemisphere, thus making it difficult to give evidence for magnetoionic coupling phenomena as a general rule.

2. Circular Polarization from the Solar Emission at 4.3 cm

The polarimeter provides outputs proportional to the total flux (S R + SL) and to the circular polarization component (SR-SL), where the indices R and L stand for right-
