A quick extraction of a red Keck I+LRIS spectrum of SN 2007fq in MCG -04-48-19 (Chu and Li, CBET #1001), obtained on July 17 2007, shows that this event is a type Ia SN. Using the superfit package (Howell et al. 2005, ApJ, 634, 1190) the best fit appears to be the peculiar type Ia SN 2001ay (see Branch et al. 2006. PASP, 118, 560; Howell & Nugent 2004, in Cosmic Explosions in Three Dimensions, ed. P. Höflich, P. Kumar, & J. C. Wheeler (Cambridge: Cambridge Univ. Press), 151). Comparisons fits with SN 2001ay, as well as the normal SN 1999ee can be see here:SN2007fq_vs_2001ay.pdf"> http://www.astro.caltech.edu/~avishay/SN2007fq_vs_2001ay.pdf andSN2007fq_vs_1999ee.pdf"> http://www.astro.caltech.edu/~avishay/SN2007fq_vs_1999ee.pdf
