Holtzman, New Mexico State University, Las Cruces) reports the discovery of two supernovae in images obtained during July 26-28 UT using the QUEST-II camera on the Palomar Oschin 1.2-m Schmidt telescope, operated by the Palomar-QUEST Consortium. Spectra (range 320-1000 nm) obtained with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope were used to classify the supernovae. A spectrum of 2007gf taken on July 29.4 showed it to be around maximum, and a spectrum of 2007gg on July 30.5 showed it to be one week past maximum. The R-band discovery magnitudes and astrometry below were derived from comparison with the USNO-B1.0 catalogue. SN 2007 UT R.A. (2000.0) Decl.
