  We have analyzed the total solar irradiance (TSI) and the spectral solar
irradiance as ultraviolet emission (UV) in the wavelength range 115-180 nm,
observed with the instruments TIM and SOLSTICE within the framework of SORCE
(The Solar Radiation and Climate Experiment) during the long solar minimum
between the 23rd and 24th cycles. The wavelet analysis reveals an increase in
the magnetic flux in the latitudinal zone of the sunspot activity, accompanied
with an increase in the TSI and UV on the surface rotation timescales of solar
activity complexes. In-phase coherent structures between the mid-latitude
magnetic flux and TSI/UV appear when the long-lived complexes of the solar
activity are present. These complexes, which are related to long- lived sources
of magnetic fields under the photosphere, are maintained by magnetic fluxes
reappearing in the same longitudinal regions. During the deep solar minimum
(the period of the absence of sunspots) a coherent structure has been found, in
which the phase between the integrated mid-latitude magnetic flux is ahead of
the total solar irradiance on the timescales of the surface rotation.
