We observed SN 2007ir (Thrasher et al., CBET 1067; Silverman et al., CBET 1077) with the Double Beam Spectrograph (DBSP) on the Palomar 200" telescope on Oct. 9.48, UT. Comparison to archival supernova spectra via the Superfit package (Howell et al. 2005, ApJ, 634, 1190), shows that SN 2007ir is a Type Ia. The spectra are quite similar to SN 1994D at 25 days after maximum light (Patat et al., 1996, MNRAS, 278, 111).
