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 to find periodicity in this layer of solar atmosphere. As expected, two pronounced periods were indicated: the rotational, about 27 d, and the activity cycle length, 11 years. Beside these, there are seen other periodicities of less significance, namely of about 5, 2.2, 1 and 0.5 year. The values of these periodicities in individual cycles 20 and 21 slightly differs, which could be related to different activity zone depths beneath the photosphere.
