Birchall, Institute for Astronomy, University of Hawaii, Hilo; and J. Holtzman, New Mexico State University, Las Cruces) reports the discovery of four supernovae in images obtained during July 13-14 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 each supernova. R-band discovery magnitudes and astrometry are derived from comparison with the USNO-B1.0 catalogue. The following table summarizes the discovery information, including redshifts (z). SN 2007 UT R.A.
