As one of its core programs, the SDSS II is conducting a Supernova survey over 3 Fall seasons (2005-8) with the primary goal of obtaining well measured multi-band light curves of ~200 type Ia supernovae (SNe) for the study of cosmology and supernova systematics. The survey is conducted by repeat scanning of a ~300 square degree region (~150 square degrees every other night) with the SDSS 2.5 meter telescope. The SDSS will primarily measure SNe Ia in the redshift range z=0.05-0.35, a 'redshift desert' where relatively few SNe have been measured by previous searches. Follow-up spectroscopy and additional imaging is provided by a variety of telescopes, including the ARC, HET, Subaru, WHT, MDM, UH88, NMSU 1m, WIYN, VATT, and the INT. The Carnegie Supernova Project is carrying out NIR imaging on a subsample of the confirmed SNe. From early Sept. to mid-October (the time of submission of this abstract), 52 spectroscopically confirmed SNe Ia were found. We describe the SN survey and present highlights from the Fall 2005 campaign.
