The Dark Energy Survey (DES) will begin in 2012, and will use the Dark Energy Camera (DECam) to observe 5000 sq. deg. of the southern hemisphere in multiple passbands, with the primary goal of constraining the Dark Energy equation of state. A 1/32-scale precursor camera (PreCam) was constructed as a testbed for DECam hardware and software, and for obtaining preliminary observations of the DES footprint. Of most benefit to DES--and to the broader astronomical community--is PreCam's catalog of southern hemisphere standard stars observed in g,r,i,z, and Y filters. We describe the current state of this catalog, along with other interesting results from PreCam observations. We conclude with a description of prospects for future additions and refinements to the present PreCam dataset, and its ultimate impact upon DES science.
