Abstract

Correlation and spectral analysis of solar radio flux density and sunspot number near the maximum of the sunspot cycle has indicated the existence of

  1. (a)

    long period amplitude modulation of the slowly varying component (SVC) of radio emission

  2. (b)

    coronal storage over a period of the order of three solar rotations

  3. (c)

    fast decay (one solar rotation period or less) of gyromagnetic emissions from radio sources

  4. (d)

    shift in location of chromospheric sources compared to those of either the upper corona or the photosphere.
