Understanding the evolution of the Type Ia supernova rate is essential to our understanding of the star formation history of the Universe. Lately, high redshift measurements of the Type Ia rate have been receiving a lot of publicity, but understanding supernovae in the local universe is also important.In particular, comparison of detection methods and the associated rate measurements at low redshift can improve methods at higher redshift. We present a novel approach for detecting Type Ia supernovae in single epoch spectroscopic observations. Application of this method to the SDSS spectroscopic sample finds 100 supernovae resulting in a luminosity weighted rate of 0.24±0.01 SNu at z=0.1. Our measurement is in good agreement with others at low redshift. We discuss the application of this method to high redshift spectroscopic samples. This work was funded by the NSF through grant 0851007.
