The results of an absolutely calibrated radio continuum
survey of the South Celestial Hemisphere at a frequency of
1420 MHz are presented. Contour maps show the area 
for the declination range 
to
. Contour steps (50 mK TB; 3 
rms
noise) and angular resolution (HPBW 35
4) of the maps match
the already existing Stockert northern sky survey at the same
frequency. We compare flux densities of compact and extended
sources with published data from the Parkes 64-m telescope and
find excellent agreement in general. The survey maps are sensitive
enough to constrain synchrotron and thermal emission components
which might influence studies of the cosmic microwave background.
