Holtzman, New Mexico State University, Las Cruces) reports the discovery of four supernovae in images obtained on July 18 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 on July 19.3 and 19.5 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 were derived from comparison with the USNO-B1.0 catalogue. The following table summarizes the discovery information (including the redshifts, z). SN 2007 UT R.A. (2000.0) Decl. Mag. z Type 2007fy July 18.2 14 47 49.47 +29 30 16.5 20.0 0.05 II 2007fz July 18.2 16 02 05.41 +29 43 34.8 16.5 0.01 II 2007ea July 18.3 22 22 07.95 -14 18 48.3 19.0 0.03 II 2007eb July 18.5 22 42 37.33 +28 18 56.4 19.4 0.10 Ia The spectrum of 2007fz indicates that it is potentially a very young type-II supernova, with a very blue continuum and immature hydrogen features. There are numerous narrow, unidentified features blueward of 500.0 nm (rest frame). There is a P-Cyg feature with an apparent peak at 580.0 nm, probably too far to the blue to be He I 587.6-nm. A redshift of z = 0.0142 is measured by cross-correlating 2007fz's observed host spectrum with an Sa-type-galaxy template. SN 2007eb is near maximum.
