Li report the LOSS discovery of an apparent supernova (mag 17.9) on an unfiltered KAIT image taken on Feb. 12.46 UT. The new object was confirmed on earlier images taken on Jan. 18.43 (at mag 16.7) and 30.40 (mag 17.4). SN 2007V is located at R.A. = 10h27m05s.58, Decl. = -3o18'05".1 (equinox 2000.0), which is 0".3 east and 1".8 south of the center of the apparent host galaxy. KAIT images taken on 2006 Dec. 3.55 (limiting mag 18.7) and 30.47 (limiting mag 18.4) showed nothing at this position. N. Morrell, S. Gonzalez, and G. Folatelli, on behalf of the Carnegie Supernova Project, report that spectroscopy of 2007V, obtained on Feb. 13.29 UT with the 2.5-m du Pont telescope (+ WFCCD spectrograph) at Las Campanas Observatory, shows this to be a type-Ia supernova about one month after maximum light. Assuming a recession velocity of 9100 km/s for the host galaxy (LCRS B102433.3-030244; Colless et al. 2001, "The 2DF Galaxy Redshift Survey Final Data Release", http://msowww.anu.edu.au/2dFGRS/), the 'superfit' spectrum comparison code (Howell et al. 2005, Ap.J. 634, 1190) provides very good fits to spectra of SN 1996X and SN 1998bu between 28 and 32 days after maximum light.
