A coronal index (CI) derived from the limb observations of the 530.3 nm emission corona (green corona) over 1964-1987 was analyzed by the Fourier transform technique (FTT) to find periodicity in this layer of solar atmosphere. As expected, two pronounced periods were indicated: the rotational, about

It is presumed that a north-southern asymmetry of a solid-body rotation of large spots, depending on even and odd solar activity cycles (Gigolashvili and Khutsishvilil 1989, 1990) may possibly be explained by the asymmetry of the appearance of large structures with strong magnetic fields in the corr
