We report preliminary results from a successful program to detect supernovae in SDSS data from repeat imaging runs taken along the celestial equator. By subtracting new SDSS data (taken during 3 months each year during the fall), we are able to semi-automatically identify candidate SNe and provide notification to the astronomical community in time for follow-up observations. This type of "rolling search", with a cadence of 3 to 5 days, will provide early detections in all 5 SDSS passbands, as well as containing within it a set of multiband light curves for each object. We report results from Fall 2002, during which we expect to find and confirm several dozen SNe in a redshift range of 0.0 < z < 0.4. We also describe a campaign being undertaken at the Apache Point 3.5m to follow-up type Ia SNe in the SDSS passbands. This will both greatly expand the low redshift sample, upon which any cosmological results using high redshift objects must be based, and allow for the construction of an SN Hubble diagram based on light curves in the SDSS passbands. This work was supported by funding from the McDonnell Foundation, NASA, DOE and NSF.
