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 using the QUEST-II camera on the Palomar Oschin 1.2-m Schmidt telescope, operated by the Palomar-QUEST Consortium. Spectroscopy (range 320-1000 nm) obtained with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2- telescope were used to classify each. A spectrum of 2007im obtained on Sept. 7.4 UT showed it to be a few weeks past maximum. A spectrum of 2007in obtained on Sept. 10.5 show it to be a week past maximum. Spectra of 2007io and 2007ip obtained on Sept. 12.5 showed both objects to be near maximum. The R-band discovery magnitudes astrometry tabulated below were derived from comparison with the USNO-B1.0 catalogue. SN 2007 UT R.A. (2000.0) Decl.
