  We present multi-frequency maps of a portion of the Galactic Plane centered
on a declination of -60 degrees with resolutions ranging from 0.2 to 0.9
degrees. The maps are optimized to detect unresolved source emission and are
cross-calibrated against the planet Jupiter. We discuss six millimeter-bright
regions, three of which are visible in all bands, and list measured flux
densities. Variability is limited to less than 3.8% for all sources seen at 31
and 42 GHz and less than 10% at 144 GHz. Fractional polarization limits smaller
than 0.08 are measured for all sources seen at 31 and 42 GHz. No fractional
polarization limits are reported at 144 GHz.
