We have imaged an 11.5 deg2 region of sky toward the South Ecliptic Pole (R.A. =04h43m, decl. =–53°40', J2000) at 24 and 70 μm with MIPS, the Multiband Imaging Photometer for Spitzer. This region is coincident with a field mapped at longer wavelengths by AKARI and BLAST. We discuss our data reduction and source extraction procedures. The median 1σ depths of the maps are 47 μJy beam–1 at 24 μm and 4.3 mJy beam–1 at 70 μm. At 24 μm, we identify 93,098 point sources with signal-to-noise ratio (S/N) ≥5 and an additional 63 resolved galaxies; at 70 μm we identify 891 point sources with S/N ≥6. From simulations, we determine a false detection rate of 1.8% (1.1%) for the 24 μm (70 μm) catalog. The 24 and 70 μm point-source catalogs are 80% complete at 230 μJy and 11 mJy, respectively. These mosaic images and source catalogs will be available to the public through the NASA/IPAC Infrared Science Archive.
