Birchall, Institute for Astronomy, University of Hawaii, Hilo; and J. Cough and J. Holtzman, New Mexico State University, Las Cruces) reports the discovery of four supernovae in images obtained during Aug. 15-19 using the QUEST-II camera on the Palomar Oschin 1.2-m Schmidt telescope, operated by the Palomar-QUEST Consortium (cf. CBET 1031). Spectra (range 320-1000 nm) were obtained on Aug. 21.4 and 21.5 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope; 2007gt was then ten days past maximum, 2007gu was a few days past maximum, and 2007gv was near maximum. R-band discovery magnitudes and astrometry were derived from comparison with the USNO-B1.0 catalogue. SN 2007 UT R.A. (2000.0) Decl.
