Connection of the solar constant variations with the age and activity of sunspots
Abstract
Sunspot-related decreases of the solar constant appear mainly to depend upon the activity of the sunspot groups. At the time of the irradiance dips the increased solar radio flux on 260 MHz suggests that MHD-waves could play an important role in the transportation of the missing energy in the solar constant decreases. With disappearing sunspot activity, in the second part of 1984, there were no large variations in the solar constant or in the 260 MHz radio flux. This could indicate that the level of the ``activity layers'' in the convective zone would be nearer to the photosphere at the time of the solar minimum than of the maximum.
