SNID ( Blondin, S. & Tonry, J. L. 2007. ApJ, 666, 1024) gives credible matches to type 1a supernovae pre maximum at the redshift of the probable host. (Redshift from NED). Removing contamination from the host galaxy in the spectrum using the SDSS galaxy spectrum as a template improves the quality of the match. Example matches are attached.
