Holtzman, New Mexico State University, Las Cruces) reports the discovery of eleven supernovae in images obtained during June 30-July 8 UT using the QUEST-II camera on the Palomar Oschin 1.2-m 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 during July 4-9 were used to classify each new object. The R-band discovery magnitudes and astrometry tabulated below were derived from comparison with the USNO-B1.0 catalogue. SN 2007 UT R.A. (2000.0) Decl.

A spectrogram from July 4.4 shows 2007fh to be about one week after maximum. A spectrogram from July 9.3 shows 2007fi to be at maximum. A spectrogram taken of 2007fn in UGC 1963 (z = 0.017 from de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies) on July 9.6 shows that it is similar to the spectrum of SN 2000H about 1 month after maximum.
