The proposed SDSS II includes a Supernova Survey that will encompass three 3-month seasons, Sept.-Nov. 2005-7, with the aim of obtaining well-sampled, well-calibrated, multi-band lightcurves for ~200 Type Ia supernovae in the redshift `desert' z = 0.1-0.35. This sample, with photometric data over ~250 square degrees imaged every other night from a single instrument with well-understood wavelength response, will yield improved constraints on the dark energy and enable detailed study of the systematics of the Ia population as they affect the use of these objects as standard candles for cosmology. The survey will include spectroscopic follow-up on other telescopes for SN identification and redshift determination, near-infrared imaging follow-up to constrain host galaxy extinction, and multi-epoch spectrophotometry for a subsample in order to obtain improved K corrections. In preparation for SDSS II, the collaboration is carrying out 20 nights of repeat imaging on the SDSS 2.5m telescope in Fall 2004, with follow-up planned on the ARC 3.5m, HET, and other telescopes. This talk will describe the goals, status, and early results from the SDSS Supernova Survey. It will also briefly describe the sample of nearby supernovae discovered in SDSS galaxy spectra.

Funding for the Sloan Digital Sky Survey (SDSS) has been provided by the Alfred P. Sloan Foundation, the Participating Institutions, the National Aeronautics and Space Administration, the National Science Foundation, the U.S. Department of Energy, the Japanese Monbukagakusho, and the Max Planck Society.
