The Spitzer First Look Survey (FLS) was the initial Director's Discretionary Time program executed on the observatory.
The Extragalactic First Look Survey is composed of 4 square degrees of imaging with MIPS and IRAC centered at J1718+5930. Spitzer and ancillary data are available using spatial and visualization tools.
The Galactic First Look Survey spent 36 hours mapping regions of the Milky Way, with the goal of characterizing cirrus and source counts in different Galactic environments. The data are available from the Spitzer Heritage Archive.
The Ecliptic First Look Survey concentrated on two 0.13 square deg fields at a solar elongation of 115 degrees and ecliptic latitudes (b) of 0 degrees and +5 degrees. The FLS-EPC explored the small asteroid counts at 8 and 24 microns, with a detection limit down to 0.08 and 0.8 mJy, respectively, and a completeness limit almost twice as deep as the 8 micron equivalent flux density of the previous deepest mid-IR survey. The FLS-EPC also provided initial characterization of the zodiacal light near the ecliptic plane. The data are available from the Spitzer Heritage Archive.
